MATLAB: A file houseafford.dat stores on its three lines years, median incomes and median home prices for a city. The $ amounts are in thousands. For example, it might look like:

2004 2005 2006 2007 2008 2009 2010 2011

72 74 74 77 80 83 89 93

250 270 300 310 350 390 410 380

load the information from the file into a matrix. The ratio of the home price to the income is called the housing affordability index. Compute this for every year and plot it. The x-axis should show the years (e.g., 2006 to 2013). Store the handle of the plot in a variable and use get to see the properties and set to change at least one.
