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

function 1 is a horizontal line so the rate of change is 0

function 2 is a linear function so the rate of change is the slope of y = 5x + 4

from there simply subtract (rate of change function 2) - (rate of change function 1)
