2 Parallel Planes & 1 Intersecting

Topic:
Planes
In this example, 2 of the planes are coincident (as explained previously, their equations are scalar multiples of on eanother). The other plane is parallel, because its normal vector is parallel to the other normals, but it is distinct.

How many points of intersection of all three planes are there?
