Civilian Labor The table lists the percent of the female population that worked in the civilian labor force from 1980 to 2007.

(a) Find the point—slope form of the line that passes through the points (1980, 51.5) and (2007, 59.3). Let = (1980, 51.5).

(b) Use this equation to estimate the percents in 1990, 1995, and 2000 to the nearest tenth of a percent. Compare these estimates with the actual values shown in the table.
