A. The rate of change is equal.
The rate of change is equal to the change in y values divided by the change in the x-values. From the table, the values of x and y are written here in ordered pair form: (-1, 0), (0, 1), (1, 2), (2, 3). The change in y is 1 and that of x is also 1. Therefore, the rate of change is 1. From the graph, the value of change of y and x are both 1 also.
