2. Use the given information to write an equation of each line.

The bar graph below shows the percentage of never-married men (left columns) and women (right columns) ages 25-29 for four selected years. The corresponding scatter plots with lines are shown below, where x is the number of years since 1980. Use the line for the women to complete parts (a)-(c). a, fir 58.7 60- 51.7 46.2 50- 40-30 3 213 44 9 31.7 38.8 1980 1990 2000 2008 60- men. 20.38.8) 10,31.7) 30-* women 15 30 Years after 1980 Percentage Never Married % Never Manied
