i know that the normal must be <1, -3, -2>
but how am i supposed to find a point in the plane. I suppose you could try just make y and z 0 and then make x 7 to get a possible solution, but is there some rule that prevents this?
in any case, given that the entire question is finding a point, i think if i pulled some trickery like that, I will get no credit.
