The value of the expression is -24
This is because you distribute the -4 to both of the values in the parenthesis like this:
-4(7) + -4(-1)
This can be simplified to:
-28 + 4
Which equals -24
Hope this helps!
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.
It's b because you have to round up
