Two Planes Intersecting in a Line

Topic:
Planes
If two planes are not parallel nor coincident, then they must intersect along a line. In this example, the planes are x + 2y + 3z = -4 and x - y - 3z = 8. The dotted line represents the line of intersection of these two planes.

What are the normal vectors of each plane?

How many points of intersection are there between these planes?
