Find the plane that passes through the point (-1,2,1) and contains the line of intersection of the planes:
The Attempt at a Solution
First, I know that I need to find the line of intersection of the 2 planes. To do this, I used the cross product of the normal vectors to get <4,-1,-3>. This is the direction vector, but now I don't know exactly what to do. I know I need to find a point in both planes, but I'm not really sure how. I found another post which will help after I find the intersection line.
