Question 446830: 3. The linear equation
y=0.15x+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.
b. What is the slope, or rate of change, of this equation?
c. What is the y-intercept?
d. What does the y-intercept represent?
Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
(b) The slope is
(c) The y-intercept is
(d) The y-intercept would be the average
cost of gas when , or for the
year 1996, since represents
1997
