Question

*please help* The points (0, -4) and (3,2) lie on the graph of a linear function. What is the rate of change of the function?

Answer 1

rate of change = slope

slope = )y2 - y1) / (x2 - x1)
(0,-4)....x1 = 0 and y1 = -4 (pay attention to the negative sign when subbing)
(3,2)....x2 = 3 and y2 = 2
now we sub
slope(rate of change) = (2 - (-4) / (3 - 0) = (2 + 4) / 3 = 6/3 = 2 <==
