You are writing a paper for your International Business class and have come across the following information that you will include in your paper as your third graph. The information is concerning Shoe Sales in Mexico from 2006-2013, where Q is measured in tens of thousands of shoes sold and P is the price of a pair of shoes, measured in thousands of Pesos. The New York Herald-Tribune article that included the data was entitled “Mexican Shoes on Road to Recovery.” The article was written by Frank Wills and was published on page 23 in September 6, 2014 hard copy edition of the paper. The data is below:

Q             0             4             8            12           16          20           24          28

P             44           39           34          29           24           19          14           9

a. Clearly and accurately construct a line graph using Excel based on all the information above. 

b. Calculate the slope of the line you have graphed. Show all work. 

c. Interpret the slope of the line you graphed. In your interpretation be certain to mention what type of relationship this is and, very specifically, explain what the number is telling us about the behavior of the variables relative to each other.
