SOCIAL SCIENCE: Age at First Marriage Americans are marrying later and later. Based on data for the years 1990 to 2005, the median age at first marriage for men is y1 = 26.3 + 0.058x, and for women it is y2 = 24 + 0.096x, where x is the number of years since 1990.
a. Graph these lines on the window [0, 40] by [20, 30].
b. Use these lines to predict the median marriage ages for men and women in the year 2020. [Hint: Which x-value corresponds to 2020? Then use TRACE, EVALUATE, or TABLE.]
c. Predict the median marriage ages for men and women in the year 2030.
