Slope = (y2 - y1)/(x2 - x1) = (-1 - 17)/(-8 - (-10)) = -18/(-8 + 10) = -18/2 = -9

22. What is the average rate of change over the interval (-3, 2)? SEE EXAMPLES​
ivann1987 [24]

The average rate of change over the interval (-3, 2) is 1

<h3>Average rate of change</h3>

The average rate of change of a function, graph, table or ordered pair is simply the slope of the relation

<h3>Interval</h3>

The interval is given as: (-3,2)

From the graph, we have:

  • f(-3) = -5
  • f(2) = 0

So, the average rate over these intervals is calculated as:

m = \frac{f(b) - f(a)}{b -a}

This gives

m = \frac{f(-3) - f(2)}{-3 -2}

Substitute known values

m = \frac{-5- 0}{-3 -2}

Simplify

m = \frac{-5}{-5}\\\\

m =1

Hence, the average rate of change is 1
