MATH133 Unit 1 Individual Project A
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.
(___, ___),(___, ___)
b) Find the slope (rate of depreciation) of this line:
Answer:
Show your work here:
c) Find the linear equation of this line in slope-intercept form.
Answer:
Show or explain your work here:
d) If the rate of depreciation continues at the present rate, what will be the plane’s
value in the year 2019? Show how to use the linear equation from part c) to
obtain your answer.
Answer:
Show or explain your work here:
2) Suppose that the width of a rectangle is 5 inches shorter than the length and that
the perimeter of the rectangle is 80 inches. The formula for the perimeter of a
rectangle is P=2L+2W.
a) Set up an equation for the perimeter involving only L, the length of the rectangle.
Answer:
b) Solve this linear equation algebraically to find the length of the rectangle. Find
the width as well.
Answer: Length ______, Width ______

3) A marketing group developing online ad space is offering two payment options:
Option 1: $225 set up fee plus $10/inch of the ad
Option 2: No set up fee but $25/inch of the ad
Let x = inches of the proposed ad, for example, x = 2 for a column ad that is 2 inches
long.
a) Write a mathematical model representing the total ad cost, C, in terms of
x for the following:
Option 1: C=_________________
Option 2: C=_________________
b) How many inches of ad space would need to be purchased for option 1
to be less than option 2? Set up an inequality and show your work
algebraically using the information in part a).
Answer:
Show your work here:
4) Graph the equation on separate graphs by completing the tables and plotting
the points. You may use Excel or another web-based graphing utility.
a) Complete the table using the given values of x and the equation y = -3x + 7.
x y

b) Graph the equation here by plotting the points from your table. For help on
creating your graph in Excel and inserting graphs into a Word Doc please see the
tutorial in the Assignment List.
