3. The linear equation

represents an estimate of the average cost of gas for year x starting in 1997. The year 1997 would be represented by x = 1, for example, as 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 you arrive at your answer?
