If 2 points determine a line, then a line contains infinitely many planes.
Infinitely many planes contain any two given points- it takes three (non-collinear) points to determine a plane.
Given a line, there are an infinite number of different planes that it lies in.
Exactly one.
Only one plane can contain three specific points.
Three points can lie in more than one plane if they are not collinear. If the three points are non-collinear, they define a unique plane, but if they are collinear, they can lie on infinitely many planes that contain that line. Additionally, if you consider different orientations or positions of planes that intersect the line formed by the collinear points, these also contribute to the existence of multiple planes. Therefore, the arrangement and relationship of the points determine how many planes can contain them.
Infinitely many planes contain any two given points- it takes three (non-collinear) points to determine a plane.
Infinitely many planes may contain the same three collinear points if the planes all intersect at the same line.
Given a line, there are an infinite number of different planes that it lies in.
One.
There are no planes containing any number of given points. Two points not the same define a line. Three points not in a line define a plane. For four or more points to lie in the same plane, three can be arbitrary but not on the same line, but the fourth (and so on) points must lie in that same plane.
Exactly one.

There will always be a single plane through all three points.
