Question 577304: The line y=0.15x + 0.79 represents an estimate of the average cost of gas each year. The line 0.11x - y= -0.85 estimates the price of gas in January of each year.
a) Do you expect the lines to be intersecting, parallel, or perpendicular? Why?
b) Use the equations of the lines to determine if they are parallel. What did you find?
c) Did your answer in part b confirm your expectation from part A?

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