The minimum hourly wage, $y$ (in dollars per hour), in the United States can be approximated by the equation $y=0.14 x+1.60 .$ In this equation, $x$ represents the number of years since $1970(x=0$ represents $1970, x=5 \text { represents } 1975, \text { and so on }) .$
A. Use the equation to approximate the minimum wage in the year 1980
B. Use the equation to predict the minimum wage in 2010 .
C. Determine the $y$ -intercept. Interpret the meaning of the $y$ -intercept in the context of this problem.
D. Determine the slope. Interpret the meaning of the slope in the context of this problem.
