Explain whether y = 4x + 8 is a linear function or nonlinear function.
It is linear because the rate of change is 4/1 or 4. The line of the graph is straight.

Which section of the function is constant? Why?
C, because the y-value remains the same. The rate of change is 0 (there is not change = constant).
