The y-intercept will give the estimated cost of tuition in 2000 (see my video answer in the other part of the question for how to find the value of the y intercept).

"let x be the number of years since 2000 and let y be the cost of tuition." The y-intercept is the value of y when x=0. So, when the number of years since 2000 equals zero (that is, year 2000), the cost of tuition is the (extrapolated) cost of tution in year 2000. NOTE that this is OUTSIDE THE GIVEN RANGE OF THE FUNCTION.06/09/23
