Question

The minimum hourly wage, y (in dollars per hour), in a country can be approximated by the equation y = 0.12x + 1.18. In this equation, x represents the number of years since 1970 (x=0 represents 1970, x=5 represents 1975, and so on). Federal Minimum Hourly Wage by Year y = 0.12x + 1.18 Minimum Wage ($/hr) Year (x = 0 represents the year 1970) (a) Use the equation to approximate the minimum wage in the year 2005. The minimum wage in 2005 was approximately $ 5.38 . (b) Use the equation to estimate the minimum wage in the year 2010. The minimum wage in 2010 was approximately $ 5.98 . (c) Determine the y-intercept. Interpret the meaning of the y-intercept in the context of this problem. The y-intercept is ( , ). In the year the minimum wage was approximately $ per hour. (d) Determine the slope. Interpret the meaning of the slope in the context of this problem. The slope is . This indicates that the minimum wage has (Choose one) by approximately $ per year during this period.
