The following table shows thetotal adjusted gross income (AGI), in trillions of dollars, reported to the IRS in the given year.Year2009201020112012AGI (trillions)7.68.18.69.1(a) Show that the data are linear.The difference in the total AGI (in trillions) from 2009 to 2010 is.5the difference from 2010 to2011 isand the difference from 2011 to 2012 is .5. Because these values are allthe samethe function is linear.(b) Let t denote the time in years since 2009, and let A denote the total adjusted gross income. Find a linear model for Aas a function of t.A(t)(c) Identify the slope of the linear model you found in part (b)trillion dollars per yearExplain its meaning in practical terms.The slope is the total amount, in trillion of dollars, AGI was increasing by each year in this period.The slope is the total amount, in trillion of dollars, AGI was increasing by each month in this period.The slope is the number of months it will take the AGI to increase by one trillion dollars.OThe slope is the number of years it will take the AGI to increase by one trillion dollars.The slope is the initial amount, in trillion of dollars, of the AGI.Question
