Do you know how to put the equation in terms of y?
OpenStudy (roadjester):
Yes, it's putting it in 3D that I don't know how to do. This isn't a xy-plane problem which is algebra. It's Calculus III.
OpenStudy (shane_b):
You only have 2 dimensions in the equation...x and y.
OpenStudy (roadjester):
True, which is why I need help...
OpenStudy (shane_b):
x+y=2 is just a line. You can draw it in 3D using just the XY plane...with the Z axis in there for completeness.
