if p is the plane of vectors in R4 satisfying x1+x2+x3+x4-0, write a basis for P perp. Construct a matrix that has P as its nullspace...

hmm

does that mean the linear combination of the vectors = 0? if so i can write the null space and that'd be perpendicular to the row space... this newer stuff is kinda tough to swallow.
