Understanding Linear Equations for Tuition Costs

The video tutorial explains how to derive a linear equation to represent tuition costs at a university from 1990 to 2005. It covers the calculation of the slope and intercept, and how to use the equation to predict future tuition costs. The tutorial also demonstrates how to determine the year when tuition will reach a specific amount.

What was the tuition cost per credit hour in 1990?
