The graph of a function is given Determine the average rate

The graph of a function is given. Determine the average rate of change of the function between the indicated points on the graph. (Assume that the points lie on the grid lines.)

Solution

Average Rate of change of function = (Change in Y value)/ (Change in X value)

                                                   = (y(5)- y(0)) / (5-0)

                                                   = (2- 5)/5 = -3/5 = -0.6

Your Answer is correct. If its not work then try once putting answer as 0.6.
