Infinite.
Infinitely many planes.
Exactly one.
-- An infinite number of different planes can intersect the same line. -- The same line can lie in an infinite number of different planes. -- An infinite number of different lines can intersect the same plane.
If 2 points determine a line, then a line contains infinitely many planes.
Infinite.
Infinitely many planes.
Exactly one.
An infinite number of planes. Picture a line and now picture planes going in every direction through the line,
Only one.
-- An infinite number of different planes can intersect the same line. -- The same line can lie in an infinite number of different planes. -- An infinite number of different lines can intersect the same plane.
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.
The intersection of two planes forms a line.
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 minimum of 2, but an infinite number of planes can intersect at the same line.
There are an infinite number of planes that pass through a pair of points. Select any plane that passes through both the points and then rotate it along the line joining the two points.
