1. The problem statement, all variables and given/known data Find the point of intersection of the lines r(t)=< 2t+1, 3t+2, 4t+3> and x=s+2 y=2s+4 z=-4s-1 Then, find the plane determined by these lines. 2. Relevant equations Intersection is when points meet. So, just equating x,y, and z variables will yield the point of intersection. 3. The attempt at a solution The point of intersection is P(1,2,3), but I'm clueless on how to find the plane with two parametric equations. It's very simple to find the plane, when they are not parametric. Could someone help?
