Which of the following best describes the average rate of change of a linear function?
a. y-intercept
b. x-intercept
c. slope
d. origin

Earlier in this chapter we have expressed linear equations using the standard form Ax + By = C. Now we're going to show another way of expressing linear equations by using the slope-intercept form y = mx + b.

In the slope-intercept form you use the slope of the line and the y-intercept to express the linear function.

Where m is the slope and b is the y-intercept.

Example

Graph the equation

rewrite in slope-intercept form

Identify the slope and the y-intercept

m = 2 and b = 1

Plot the point corresponding to the y-intercept, (0,1)

The m-value, the slope, tells us that for each step to the right on the x-axis we move 2 steps upwards on the y-axis (since m = 2)
