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

function 2
y = 8x + 12

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

3
4
5
8

8

Step-by-step explanation:

we know that

The rate of change of a linear equation is a constant that is the same that the slope

step 1

we have

The equation of the graph (function 1) is equal to

y=4

Is a horizontal line

The slope is equal to zero

so

The rate of change of function 1 is zero

step 2

The equation of the function 2 is

This is a linear equation in slope intercept form

where

the slope is equal to m=8

so

The rate of change of function 2 is 8

therefore

The rate of change of function 2 is 8 more than the rate of change of function 1
