In this video we will do examples of each of the three possibilities of how a line and a plane can intersect.  We can have NO points of intersection if the line is parallel to the plane, ONE point of intersection if the line goes right through the plane and an INFINITE number of intersection points if the line is ON the plane.   We will use the dot product of the normal to the plane and the direction vector of the line to give us our first indication of how the line and the plane are situated.
