Compare Functions

Question

A line with y-intercept (0, 8) which passes through the point (4, 0) determine if the the following function is decreasing or increasing, and compare the rates of change.

Answer 1

decreasing function. Just plot the 2 points and look at the line connecting them. It goes downhill, decreasing slope

the rate of change is a constant = slope = (8-0)/(0-4) = -2 = difference in y values divided by difference in x values
