If 2 points determine a line, then a line contains infinitely many planes.
Given a line, there are an infinite number of different planes that it lies in.

-- A line has no plane and no part of one. -- Regarding a plane, go back and look at that word "half" again.
Two planes intersect at a line. The line where they intersect pertains to both planes. In the same manner, if infinitely many planes intersect each other at the same line, then that line pertains to the infinitely many planes.
Just 1 1 plane is simply a never ending line with absolutely no width or height. 2 planes would be a flat surface with no height

An infinite number of planes. Picture a line and now picture planes going in every direction through the line,
