I have a straight line given by ________. x - y - 4z + 12 = 0 and 2x + y -2z + 3 = 0. I'm looking to convert it to the parametric form of a straight line like this: vecr = p_1 + t vecv. Is my method correct? Secondly, this is a rather long method and produces an ugly parametric form. Can I do this quicker and better?
