Re: Plotting Intersecting Planes

I appreciate all your help. I tried all three methods and they work.
Another that I tried was using the Plot3D function:

one:=Plot3D[3/4-3/4x+1/2y,{x,-10,10},{y,-10,10}];
two:=Plot3D[1/3-2/3x+4/3y,{x,-10,10},{y,-10,10}];
three:=Plot3D[5/2-1/2x+3/2y,{x,-10,10},{y,-10,10}];
Show[one,two,three]

It then show me a graph for each individual plane and the three
interesecting planes. Using my method, how could I stop Mathematica from
showing the three individual planes when it shows me the intersecting
planes?
Thanks,
Heath
