The average annual tuition and fees at all 4-year institutions in the US in 1982 was $5,230 and in 2018 was $ 11,314.Let y be the average tuition and fees in the year x, where x = 0 represents the year 1982.

a)I need 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.

b) How do I use this equation to predict the average tuition and fees at 4-year institutions in the US in the year 2030.

c) Finally how do I explain what the slope of this line means in the context of the problem.
