Hello, njr008!

Substitute the coordinates into the equations of the planes(a) Check that is a point on the intersection of the planes:

. .

. . and show that lies on both planes.

Find the direction vector of the line with: .(b) Find the parametric equations for the straight line

defined by intersection of these planes.

HINT: use the fact that the line must pass through

and be perpendicular to the normal of each plane.
