Learn about a class of equations in two variables that's called "linear equations." They are called that way because their graph is a line. These are the most basic and probably most useful equations you …

Learn to write equations in slope-intercept form for three different lines.

In this unit, we learn how to write linear equations in different forms to reveal different features of their relationships.

Write a linear two-variable equation to represent the relationship between two quantities from a graph, a written description or a table of values within a mathematical or real-world context.

Graphs of linear equations and functions questions deal with linear equations and functions and their graphs in the x y -plane. For example, the graph of y = 2 x 1 is shown below.

About this unit We can write linear equations in different forms to reveal different features of the scenarios they describe. Let's get clever. Unit guides are here! Power up your classroom with …

Learn how to find the slope-intercept equation of a line from two points on that line. If you haven't read it yet, you might want to start with our introduction to slope-intercept form.
