The rate of change is constant in the graph. find the rate of change. explain what the rate of change means for the situation.

Step-by-step explanation:

Let's take the points displayed on this graph:

(300, 3) (200, 6) and (100, 9).

Our first value in the points represents the amount of money for the resale value of a refrigerator, and the second value represents the number of years after the original purchase. So, as we can see, as the years increase, the value goes down $100 dollars every three years.

3 years after original purchase: $300

Increase years by three, value goes down by $100

6 years after original purchase: $200

The rate of change in this situation means that for every  resale three years after the original purchase, the value will decrease by $100.
