calculate

(y=mx+b) Where m is slope and b is y-int.
y=-5/6x-1
The average rate of change of the function at the interval is -8
<h3>How to determine the average rate of change?</h3>
The table that completes the question is added as an attachment
From the table, we have:
f(5) = -26
f(3) = -10
The average rate is then calculated as:
Rate = (f(5) - f(3))/(5 -3)
This gives
Rate = (-26 + 10)/(5 -3)
Evaluate
Rate = -8
Hence, the average rate of change of the function is -8

1. It is 84.
x=100%
63=75%
(63*100)/75=84
