Question

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?

Answer 1

The horizontal line at y=4 doesn't have any slope, so the answer should be relatively easy to find.  It's just the slope of Function 2.

y = 8x + 12 is the function for Function 2.  8x is the important part.

So the rate of change differing from both functions is 8.
