The graph represents function 1, and the equation represents function 2:

Function 1

A coordinate plane graph is shown. A horizontal line is graphed passing through the y-axis at y = 4.
Function 2
y = 8x + 12

How much more is the rate of change of function 2 than the rate of change of function 1? (4 points)

3

4

5

8

The rate of change of function 1 is 0 since it is a horizontal line. The rate of change of function 2 is the coefficient of x in the equation, which is 8.

So, the rate of change of function 2 is 8, which is 8 more than the rate of change of function 1.

Therefore, the correct answer is 8.
