You can have an infinite number of planes passing through three collinear points.
Infinitely many planes may contain the same three collinear points if the planes all intersect at the same line.

Only one if they are non-collinear. An infinite number if they are collinear.
Exactly one.
Exactly one.
Just one plane.
If the points are collinear, that means there's only one straight line. An infinite number of different planes can be drawn that contain one straight line.
There will always be a single plane through all three points.
Infinitely many planes contain any two given points- it takes three (non-collinear) points to determine a plane.
