Solve the problem.
-In 1995 the United States recovered 24% of its municipal solid wastes through recycling, up from 17% in 1990. Let y represent the percentage recycled and x the number of years since 1990. Find a linear equation that fits this
Data.
A) y = 0.7x - 17
B) y = 1.4x + 17
C) y = 1.4x + 24
D) y = -1.4x + 7

The slope (m) of the line is calculated by the change in percentage over the change in years, which is (24% - 17%)/(1995 - 1990) = 7%/5 years = 1.4% per year. Using the point (0, 17) for the year 1990 and the slope 1.4, the equation of the line is y = 1.4x + 17.
