Volume is the area of the base times the height of the figure. This means that the area of the base is 1x1 and then the height is 1. The volume is 1 cubic foot.
The greatest common factor is 3abc
Your graph will look like an x (ok, the y axis is at a weird place in my plot). The solution (ie., the point where the two graphs intersect) is at (-1,1).
You can also calculate this by equating the two formulas:
x+y = x-y+2 => 2y = 2 => y=1, x =-1.
depending on the size of both i would say 3 inches
