3. The linear equation represents an estimate of the average cost of gas for year x starting in 1997 (“Consumer price index,” 2006). The year 1997 would be represented by x = 1, for example, because it is the first year in the study. Similarly, 2005 would be year 9, or x = 9. a. What year would be represented by x = 4? b. What x-value represents the year 2018? c. What is the slope, or rate of change, of this equation? d. What is the y-intercept? e. What does the y-intercept represent? f. Assuming this growth trend continues, what will the price of gasoline be in the year 2018? How did
Can you figure out a on your own?
No, the problem specifically states that 1997 would be x = 1. So what would x=4 be?
4 is 3 more than 1. What year is 3 more than 1997?
