Learn to recognize if a function is linear. Created by Sal Khan and Monterey Institute for Technology and Education.

Linear equations like y = 2x + 7 are called "linear" because they make a straight line when we graph them. These tutorials introduce you to linear relationships, their graphs, and functions.

For a linear equation of the form y = mx + b, y is an increasing function of x if m is positive, a constant function of x if m is zero, and a decreasing function of x if m is negative.

Equations and functions are not the same thing, but they can be related in several ways. Watch Jesse Roe and Sal talk about the difference between equations and functions.

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 …

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both …
