Using it's concept, the average rate of change of the function over the interval 10 < x < 22 is given by:

<h3>What is the average rate of change of a function over an interval?</h3>
It is given by the change in the <u>output divided by the change in input</u>.
Over the interval 10 < x < 22, the outputs are f(10) and f(22), hence the rate of change is given by:

4/7 5/8 6/9 are some possible answers
well if you can find the slope then choose one of your ordered pair and plug them in tot he corresponding variable. since you don't know what the y intercept you basically find x which will be the y int.
