Table 12 lists fall undergraduate enrollment by gender in U.S. degree-granting institutions. The figure contains a scatter plot and regression line for each data set, where x represents years since 1980 and y represents enrollment (in millions).

(A) Interpret the slope of each model.

(B) Use the regression models to predict the male and female undergraduate enrollments in 2025.

(C) Use the regression models to estimate the first year in which female undergraduate enrollment will exceed male undergraduate enrollment by at least 3 million.
