1. The problem statement, all variables and given/known data Find the parametric equations through point (5,-1,3) parallel to the line of intersection between 2x-y+z=1 and 6x-y-z=3, where 0≤t≤1 2. Relevant equations 1. Find normal vectors for both planes 2. Take cross product of both normal planes ... 3. The attempt at a solution normal to plane 1 is <2,-1,1> normal to plane 2 is <6,-1,-1> cross product to both normal vectors is (1+1)i-(-2+6)j+(-2+6)k =2i-4j+4k=<2,-4,4> I wasn't sure how to input the point or if I am on the right track?
