Question 1085098: The average annual tuition and fees at all 4 year institutions in the US in 1982 was $10,385 and in 2012 was $23,872. Let y be the average tuition and fees in the year x, where x=0 represents the year 1982.
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.
y=
Use the equation to predict the average tuition and fees at 4 year institutions in the US in the year 2030.
Tuition in 2030 =

If 1982 is the base year, and it's the year x=0, then 2 points on your line are:
(0,10385)+(30,23872) so:
y=449.57x+10385
Tuition in 2030:
y=10385+449.57(48)
Slope indicates rate of growth in tuition per year. ☺☺☺☺
