The average annual tuition and fees at all 4-year institutions in the US in 2002 was $12,160 and in 2009 was $ 20,002. Let y be the average tuition and fees in the year x, where x = 0 represents the year 2002. Write a linear equation, in slope-intercept form, that models the growth in average tuition and fees at all 4-year institutions in the US in terms of the year x
\n" ); document.write( "You are given 2 points:: (0,12160) and (7,20002)
\n" ); document.write( "---
\n" ); document.write( "slope = (20002-12160)/7 = 7842/7 = 1120.29
\n" ); document.write( "----------------
\n" ); document.write( "Note:: (0,12160) is the y-intercept
\n" ); document.write( "Equation:: y = 1120.29x + 12160
