Machine Value. The graph represents the value of a piece of factory machinery over a ten-year period. Each point

(t, y)gives the machine's value y after t years.

a. What does the y-intercept represent?

b. What is the value of the machine after ten years?

c. How much does the machine depreciate in value each year?

d. Write a linear equation for the value of the machine after t years, for 0 ≤ t ≤ 10.

e. What does the slope found in part d represent?
