# 1
Any three non-collinear points will define a single plane. A plane is composed of an infinite number of distinct lines.
As long as at least two of them are different points, exactly one line.
7.
only 1 lines can contain 3 collinear points. Maybe you mean coplanar?
10!
There are 91 lines.
5 its 4
Two intersecting lines can always cover three non-collinear points.
