Let Lz be the line passing through the points Qz=(2, 2, -4) and Q2=(8, –-1, 2) and let L2 be the line passing through the point P=(-5, 1, -11) with direction vector d-[-1, 2, -1]". Determine whether L7 and L, intersect. If so, find the point of intersection Q. If not, find a value for the z- coordinate of P, so the resulting lines do intersect.

Let Lz be the line passing through the points Qz=(2, 2, -4) and Q2=(8, –-1, 2) and let L2 be the
line passing through the point P=(-5, 1, -11) with direction vector d-[-1, 2, -1]". Determine
whether L7 and L, intersect. If so, find the point of intersection Q. If not, find a value for the z-
coordinate of P, so the resulting lines do intersect.
