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.

Between 2 distinct points, there are an infinite number of planes that can be drawn in 3 dimensions
Through any two distinct points, exactly one line can be drawn. For 5 non-collinear points, each pair of points can form a line. The number of ways to choose 2 points from 5 is given by the combination formula ( \binom{5}{2} ), which equals 10. Therefore, 10 lines can be drawn through 5 non-collinear points.
If you only have two points, they are necessarily collinear, because a straight line can be drawn between any two points.
There are 91 lines.
If there are n points then the maximum number of lines possible is n*(n-1)/2 and that maximum is attained of no three points are collinear.
