Find the rate of change for each set of ordered pairs. what is the average rate of change of all the sets?

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.

 The answer is

Step-by-step explanation:  Let the Pairs of given points be

(i) A(-1,12) and B(6,26),

(ii) C(-1,-9) and D(3,3),

(iii) E(12,6) and F(11,13).

Now, the rate of change for pair (i) is given by

Rate of change for pair (ii) is given by

Rate of change for pair (iii) is given by

Therefore, the average rate of change for all the sets is

Thus, the answer is

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
