Question

2.

The rate of change is constant in the graph. Find the rate of change. Explain what the rate of change means for the situation.


A. –3; value drops $3 every year.

B. –1; value drops $1 every year.

C.
`-(100)/(3)`; value drops $100 every 3 years.

D. –100; value drops $100 every year.

Answer 1

you take 2 points on the graph

(3,300) and (6,200)

and then you do y2 -y1

x2-x1

you plug in the values

200-300

6-3 = -(100)/(3)

every 3 years the resale of a refrigerator decreases by 100 dollars.

its basically the rate that the price goes down for resale value of a refrigerator

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.
