Question

time (minutes)
describe the rate of change for this relationship.
the amount of water devin uses
by
per minute he
runs the sprinkler.
water used (gallons)

Explanation:

Step1: Pick two graph points

Choose (0 minutes, 0 gallons) and (10 minutes, 200 gallons)

Step2: Calculate rate of change

Rate = $\frac{\text{Change in water}}{\text{Change in time}} = \frac{200 - 0}{10 - 0}$

Step3: Simplify the expression

$\frac{200}{10} = 20$

Answer:

The rate of change is 20 gallons per minute. This means the amount of water Devin uses increases by 20 gallons per minute he runs the sprinkler.
