Answer:
Rate of change for two ordered -pairs i,e
and
is given by;

1.
(-1, 12) and (6, 26)
Then;

or

2.
(-1, -9) and (3, 3)
Then;

or

3.
(12, 6) and (11, 13)
Then;

or

Now, find the average rate of change of all the sets:
Average defined as the sum of all the observation to the number of observation.

1 2/3 = 3/3 + 2/3 = (3 + 2)/3 = 5/3
