      3x p 3y+ p 5z= 0: 2. Find parametric equations for the line of intersection of the planes x+ y z= 1 and 3x+ 2y z= 0. Also nd the angle between these two planes. To nd a point on this line we can for instance set z= 0 and then use the above equations to solve for x and y. In this case we get x= 2 and y= 3 so ( 2;3;0) is a point on the line.
