Create the required linear function an use it to answer the question.
-In 1995 the United States recovered 26% of its municipal solid wastes through recycling, up from 17% in 1990. Let P represent the percentage recycled and t the number of years since 1990. Based on
These two data points, create a linear equation for the function that describes how P varies as a Function of time.
A) $P = 0.9 t - 17$
B) $P = 1.8 t + 17$
C) $P = - 1.8 t + 7$
D) $P = 1.8 t + 24$

Quizplus · Accepted Answer

The slope of the line is calculated as the change in percentage divided by the change in years: (26% - 17%) / (1995 - 1990) = 1.8. The equation of the line is P = 1.8t + 17, where 17 is the percentage in 1990.
