Chapter 8, Problem 21MCQ

To determine

To calculate: To find the rate of change for the linear function

Answer to Problem 21MCQ

Rate of change is $-16$

Explanation of Solution

Given information: Function table is

Water in Bucket
Time (s)	Amount of Water (oz)
x	y
2	80
4	48
6	16

Formula Used:

Rate of change of linear function is the rate that describes how one quantity changes in relation to another quantity.

Calculation:

Function table is given as follows:

Water in Bucket
Time (s)	Amount of Water (oz)
x	y
2	80
4	48
6	16

Rate of change is calculated as

  $\begin{array}{l}Rate=\frac{48-80}{4-2}\\ Rate=\frac{-32}{2}\\ Rate=-16\end{array}$

Conclusion:

Hence, rate of change is $-16$
