Question 257554
The line y=0.15x+0.79
represents an estimate of the average cost of gasoline for each year.
------------------
The line 0.11x-y=-0.85
estimates the price of gasoline in January of each year
--------------------
a) Do you expect the lines to be intersecting, parallel, or perpendicular? Explain your reasoning.
They will intersect, because the slopes are different.
----------------------
b) Use the equations of the lines to determine if they are parallel. What did you find?
They're not, the slopes are different.
-------------------
c) Did your answer to part b confirm your expectation in part a?
Yes
