The slope of the line representing the change in tuition is calculated using the formula $\frac{y_2 - y_1}{x_2 - x_1}$, where $(x_1, y_1)$ and $(x_2, y_2)$ are the given points. Substituting the given values, we get $\frac{3216 - 3024}{1998 - 1997} = \frac{192}{1} = 192$. This means the tuition increased by \$192 per year.
