Two Planes Intersecting in a Line

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?
