Question 315658: 3. The linear equation y=0.15 + 0.79 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.

c.What does the y-intercept represent?

I think the y-intercept is the cost of gas at the beginning of 1997
It is not an average until x+=+1 which is the end of 1997
