Two planes may intersect, be parallel, or coincide .
If two planes intersect, then the set of common points is a line that lies in both planes. Two parallel planes can not intersect.
The intersection of two planes that do not coincide (if it exists) is always a line.
If an intersection of the planes does not exist, the planes are said to be parallel.

Answer:
Step-by-step explanation:
y - 7 = -3(x - 2)
y - 7 = -3x + 6
y = -3x + 13
Here we have 2 variables we need to calculate:
x - how many Volvos Jane sold
y - how many Volvos Melissa sold
We write system of equations:
x = 8*y
x - y = 35
------------
8y - y = 35
7y = 35
y = 5
x = 8*5 = 40
Jane sold 40 cars.
It is 13 miles between the Opera House and Bryan's home.
