I'm not going to do your entire 10 question homework assignment.
1. If the car hasn't moved since it was filled with 22 gallons of gas, then 
and 
. But when the gas is gone (
), at 22 mpg, the car must have gone 440 miles (20 times 22). That gives two points on the 
plane, namely )
and )
.
Use the two point form of an equation of a line:
(x\ -\ x_1) )
where )
and )
are the coordinates of the given points.
(d\ -\ 0))
