Question

1. Cost of Tuition In 2000, the average cost of tuition
and fees at private four-year colleges was $16,200,
and in 2005 it was $20,100. Sketch a line that passes
through the points (2000, 16200) and (2005, 20100).

2. Rate of Change in Tuition Calculate the slope of
the line in your graph. Interpret this slope as a rate of
change.
3. Modeling Tuition Find the slope–intercept form of
the line in your sketch. What is the y-intercept and
does it have meaning in this situation?
4. Predicting Tuition Use your equation to estimate
tuition and fees in 2001 and compare it
