Undergraduate enrollment. Table 8 lists enrollment in U.S. degree-granting institutions for both undergraduate and graduate students. A linear regression model for undergraduate enrollment is

y = 0.17x + 10.1

where x represents years since 1980 and y is undergraduate enrollment in millions of students.

(A) Draw a scatter plot of the undergraduate enrollment data and a graph of the model on the same axes.

(B) Predict the undergraduate student enrollment in 2016 (to the nearest 100,000). (C) Interpret the slope of the model.
