Hello, I have been trying to tackle vectors over the weekend, but cant seem to get this one right. I have two lines, s(1,2,1) and (9,6,0) + t(0,1,-1). The orthogonal vector is v(-3,1,1) found using cross product. How can i find the equation of a line say P parallel to v(-3,1,1) which intersects both lines? Thanks.
