Use a graphing calculator to find linear model data for the men's 100-meter freestyle given in the table. The regression model represents the winning time on the right, where x is the number of years since 1980 (in seconds). Do the same for the women's 100-meter freestyle data. Do these models indicate that the women will eventually catch up with the men?100 Meter Freestyle Men Women1980 50.40 54.791984 49.95 55.921988 48.61 54.931992 49.02 54.651996 48.74 54.582000 48.30 53.832004 2008 47.21 51
