I interpret this as meaning that the direct sum of the line and plane, as vector spaces is . One choice is the line perpendicular to the plane which has direction vector .

Again, there are an infinite number of answers. The simplest thing to do is to choose lines orthogonal to L: and [maht]L_2= t(0, 1, 1) will work.2) .

Find 2 straight y in such that
