    the given vectors are A=<1, -1, 0> and B=<0, 1, -1> a vector normal to both A and B is given by cross product N= A X B N=<1, -1, 0> X <0, 1, -1> = <1, 1, 1> we know that equation of a plane is in the form ax+by+cz=d and N=<a, b, c> substitute the components of N, we get the plane x + y +z =d we know that (0,0,0) is a point on the plane, substitute for x,y and z in the above equation to get d=0 thus x+y+z=0 is the required plane. let x=u and y=v then z=-u-v thus equation of the surface in parametric form s: (u, v, -u-v)
