In 2000, the minimum wage in washington was $6.50 per hour. in 2010, it was $8.55 per hour.
(a) if x is the number of years past 2000 (so in 2000, and in 2010, ), and y is the minimum wage per hour, write two ordered pairs representing the minimum wages given.
(b) what is the slope of the line between these two points? what does the slope specifically represent here?
(c) what is the y-intercept? what does the y-intercept specifically represent here?
(d) find the equation of this line – write your final answer in slope-intercept form.
(e) write your equation as a function of x.
(f) if you do not earn a college degree and you are earning minimum wage in 2020, what do you predict you will be earning per hour?
1. in 2002, the greatest number of movie tickets in a single year were sold in america, at 1.58 billion. this is down to 1.27 billion (annualized) for 2010.
(a) write the linear equation modeled by these two points in slope-intercept form (let in 2000).
(b) interpret the slope specifically in real world terms. what reasons could you give for this trend?
(c) interpret the y-intercept specifically in real world terms, and why is this not true given the original description of the data? (if you didn’t use in 2000, your answer here will be wrong.)
