FAQs

What does X stand for in Y MX? ›

In the equation y = mx + b, m is the slope of the line and b is the intercept. x and y represent the distance of the line from the x-axis and y-axis, respectively. The value of b is equal to y when x = 0, and m shows how steep the line is. The slope of the line is also called the gradient.

y = mx + c is a linear equation and the variables x and y relate to coordinates on the line. When we input a value for x into the equation y = mx + c , we get a result for y . This means that x is an independent variable, and y is a dependent variable as it is determined by the value of x .

Algebra 1 is a high school math course exploring how to use letters (called variables) and numbers with mathematical symbols to solve problems. Algebra 1 typically includes evaluating expressions, writing equations, graphing functions, solving quadratics, and understanding inequalities.

m is the slope of the line (change in y/change in x) and b is the y intercept of the line (where the line crosses the y axis).

The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables.

The x value of the point (x, y) is known as the abscissa. It represents the distance of the point from the origin or along the horizontal x-axis. The y value of the point (x, y) is known as the ordinate. It represents the vertical or perpendicular distance of the point from the origin or from the x-axis.

Cartesian points are written as xy pairs in parentheses, like so: (x, y). To graph a point, first locate its position on the x-axis, then find its location on the y-axis, and finally plot where these meet.

Some schools may offer Algebra I in either 9th/10th grade OR 11th/12th grade, but not both. Nonetheless, it is important that students have access to Algebra I sometime in their high school career.

College Algebra is not difficult if you've taken Pre-Algebra and Algebra in the past and done well. However, if you haven't done well, or it's a been a while since you've taken Pre-Algebra and Algebra, College Algebra will be difficult.

9th grade math usually focuses on Algebra I, but can include other advanced mathematics such as Geometry, Algebra II, Pre-Calculus or Trigonometry. This is the year when they formalize and extend their understanding and application of quadratic and exponential functions as well as other advanced mathematical concepts.

What does the M represent? ›

Answer and Explanation: In the formula for the slope-intercept form of a linear equation, m represents the slope of the line. The formula for slope-intercept is y = mx + b.

It is not known why the letter m was chosen for slope; the choice may have been arbitrary. John Conway has suggested m could stand for "modulus of slope." One high school algebra textbook says the reason for m is unknown, but remarks that it is interesting that the French word for "to climb" is monter.

The meter is the standard unit of measuring length in the International System of Units (SI). Its symbol is “m” and it is one of the seven base units of the SI system.

It's called the Applical axis as it is used for many different applications, as in computer engineering the Applical axis is used as intensity when plotting two wave forms on a Cartesian plane and in physics it's used as depth.

When they are, the z-coordinate is sometimes called the applicate. The words abscissa, ordinate and applicate are sometimes used to refer to coordinate axes rather than the coordinate values.

In the XY sex-determination system, the female-provided ovum contributes an X chromosome and the male-provided sperm contributes either an X chromosome or a Y chromosome, resulting in female (XX) or male (XY) offspring, respectively.

In algebra, when we preceed a variable by a number, we multiply. In the same way, xy means multiply the variable x by the variable y and 7xy means multiply the variable x by the variable y and multiply the whole thing by 7.

XY Scatter Plot

A Scatter Plot is an XY chart in which we draw data points based on two numeric values. One value determines the horizontal (X) position, and the other value determines the vertical (Y) position.

A y-axis is the vertical axis on the Cartesian coordinate plane. The y-axis starts at negative infinity and increases to positive infinity. The y-axis is also the starting, or 0 point, for measuring how far a point extends horizontally on a graph.

Can I fail algebra 1? ›

Students who fail Algebra I are required to recover the credit during high school to earn a diploma, and online credit recovery courses have become a popular strategy in schools and districts around the country.

Spielhagen found that those who took Algebra 1 in eighth grade did as well as similar students who took it in ninth grade. Those taking the course in eighth grade “stayed in the mathematics pipeline longer and attended college at greater rates” than similar students who took it in ninth grade, Spielhagen said.

Seventh grade is a challenging year for many reasons. Socially, students are in the heart of middle school and all of the drama that it brings. In many subjects, the work gets harder too! In math, concepts begin to jump from concrete to more abstract, making 7th grade algebra a challenging course for many students.

What is the Hardest Math Class in High School? In most cases, you'll find that AP Calculus BC or IB Math HL is the most difficult math course your school offers. Note that AP Calculus BC covers the material in AP Calculus AB but also continues the curriculum, addressing more challenging and advanced concepts.

Algebra is overwhelming for many students because it's the first math class they take where they must wrestle with variables, abstract concepts, and creative problem solving. And there's often not enough done in the classroom to connect Algebra to their everyday lives and explain why it's worth understanding.

Students who begin Algebra 1 before 9th grade must earn a minimum score 80% on the Algebra 1 (High School) Readiness Test, and earn a minimum score of 80% on the Geometry Readiness test (or other CWCS-approved Algebra proficiency exam) upon completion of Algebra 1.

Remember that Grade 9 Math is challenging and requires a lot of hard work to succeed. Be patient and confident in your abilities! At Success Tutorial School, we offer several programs to assist students who are taking or are planning on taking Grade 9 Math.

Grade 8 Algebra is a high school level Algebra 1 course, and is the first course on their growth in upper level mathematics. The fundamental purpose of this course is to formalize and extend the mathematics that students learned through mastery of the middle school standards.

California joins Minnesota as the only states with a requirement that all students take algebra in 8th grade.

Using the slope-intercept form, the slope is 1 .

How do you write xy 2 in slope-intercept form? ›

Thus the graph is a parabola passing through origin.

Using the App. Press the PRGM button on your TI-84 calculator and locate the "XGRAPH" entry in your program list. Press the ENTER key, causing "prgmXGRAPH" to appear on your screen; press ENTER again to launch the app. When prompted, enter your equation but use the letter ​X​ instead of ​Y​.

Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values.

If two equations are both in slope-intercept form, you can easily using substitution to solve the system by putting one value of y equal to the other value of y (since in both equations, y is equal to something). From there, use inverse operations to solve for x.

Answer and Explanation: In slope-intercept form, the linear equation 2x + y = 2 would be written as y = -2x + 2.

Answer and Explanation: The slope of the line is -6 and the y-intercept is 2.

Convert the standard form equation x+y=2 to slope-intercept form. To convert from standard form to slope-intercept form, all we have to do is rearrange our equation to solve for y and then double check that our terms are in the correct order. So to do that with this equation, we have to subtract x from both sides.

y = 2 is a horizontal line that crosses the -axis at 2. y = − 2 is a horizontal line that crosses the -axis at -2.

The difference in the graph of y = -6x² + 4 and the graph of y = -6x² is a shift in the vertex position.
