1. At what rate is the value of the laptop changing?
2. At what rate is the value of the color printer changing?
3. What is the value of the color printer after 2 years?

Answer 1

There must be two graphs

Answer 2

The one you posted only shows laptops

Answer 3

rate of change of value of laptop = slope of line. looks like it decreases from 3500 to 0 in seven years, so rate of change is
\[\frac{-3500}{7}=-500\] or -500 per year

Answer 4

You can find the rate by observing where the line hits the x and y axes

Answer 7

Answer 8

Answer 9

same price so started at $3500
