Step-by-step explanation:
Let the slope of one line be 's' , then according to the given condition that the slope of second line is negative reciprocal of the first , We obtain the slope of the second line as .
So, the product of both the slopes is given by
This shows that whatever the slopes may be if they are negative reciprocal of each other then their product will always be -1

Therefore, the average rate of change is 2.
Step-by-step explanation:
The average rate of change of for over the interval will be the slope of the secant line connecting the 2 points.
To calculate the average rate of change of f(x) on the interval [a, b] is:
The average rate of change between (4, -4) and (8, 4) will be:
Therefore, the average rate of change is 2.
