1)
The following graph shows the depreciation for the corporate airplane from 2006
to 2009.
The plane was purchased new in 2006; therefore,
x
= 0 represents the
year 2006.
X – axis (horizontal) = years starting from 0 = 2006 and increasing by 0.5 years
Y – axis (vertical) = price in $ amounts from 24,000 to 240,000
a)
List the coordinates of two points on the graph in (
x
,
y
) form.
The numbers on
the horizontal axis are 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, and 3.5.
(___, ___),(___, ___)

d)
If the rate of depreciation continues at the present rate, what will be the plane’s
value in the year 2017?
Show how to use the linear equation from part c) to
obtain your answer.
