What type of association is shown by the data in the scatter plot? In the graph of scatter plot, the range of the x axis is zero to fifty and the range of the y axis is zero to sixty by increment of ten. On the x axis zero, twenty, forty are labeled and on the y axis zero, twenty, forty, and sixty are labeled. On the graph, there are points at (20, 5), (10, 10), (10, 10.2), (8, 20), (5, 30), (1, 35), (2, 40), (10, 45), and (1, 50).

A. positive association
B. negative association
C. no association
D. trend association

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.
