Describe the solution set of the ff cases, given the linear system
a_1x + b_1y + c_1z = d_1 (Plane 1)
a_2x + b_2y + c_2z = d_2 (Plane 2)
a_3x + b_3y + c_3z = d_3 (Plane 3)

(d) Plane 1 and Plane 2 intersect in a line L that is parallel to Plane 3.
(e) Plane 1 and Plane 2 intersect in a line L that lies in Plane 3.
(f) Plane 1 and Plane 2 intersect in a line L that intersects Plane 3 in a single point.
