the graph represents function 1, and the equation represents function 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

The graph is the function  y = 4 .
You may not remember what the slope of a horizontal graph is,
and when you look at that equation, you might not recognize its
slope right away.  It helps to write the equation as

                                       y = 0x + 4

and that reminds you that the slope of a horizontal line is zero.

Function 2 . . . y = 8x + 12 . . . has a slope of  8 .

The slope of Function-2 is  (8 - 0) = 8 more than the slope of Function-1.
