Question

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

A coordinate plane graph is shown. A horizontal line is graphed passing through the y-axis at y = 3.

Function 2
y = 5x + 4

How much more is the rate of change of function 2 than the rate of change of function 1?

Answer 1

The rate of change of Function 2 is 5, the coefficient of x.
The rate of change of Function 1 is 0, because there is no change.

The rate of change of function 2 is 5 more than the rate of change of function 1.
