2. Examine the rise in gasoline expenses from 1997 to 2006. The terms of regular unleaded gasoline in January 1997 was $1.26, and in January 2006, the price of regular unleaded gasoline was $2.31 (Consumer price index, 2006). engross the coordinates (1997, 1.26) and (2006, 2.31) to find the slope, or rate of change, between the two points. picture how you arrived at your answer.
Divide the rise in gas prices by the by the number or stratums that has passed.
m = 1.26-2.31/1997-2006
m = 1.05/9
m = 7/60
3. The linear equation
represents an appraisal 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 low gear year in the study. Similarly, 2005 would be year 9, or x = 9.
f. What year would be represented by x = 4?
The year 2000
g. What x-value represents the year 2018?
21
h. What is the slope, or rate of change, of this equation?
0.15
i. What is the y-intercept?
0.79
j.
What does the y-intercept represent?
The y-intercept represents where the price of gas started in 1997.
k. Assuming this growth contract continues, what will the price of gasoline be in the year 2018? How did you arrive at your answer?
Plug in x 21 for year 2018
y = .15(21) + .79 y = 3.94
4. The line
represents an estimate of the average cost of gasoline each year. The line
estimates the price of gasoline in January of each year (Consumer price index, 2006).
l. Do you expect the lines to be intersecting, parallel, or perpendicular? Explain your reasoning.
I would expect the lines to intersect because they do not...If you want to get a full essay, order it on our website: Orderessay
