only 1 lines can contain 3 collinear points. Maybe you mean coplanar?
Three lines are determined by three points unless the points are all on the same line ( i.e. co-linear)
depend how many points are them
3 non-coplanar (pairwise) lines for 3 dimensional space.
As long as at least two of them are different points, exactly one line.

Coplanar lines can intersect an infinite amount of times.

There are 13*12/2 = 78 lines.

In classical or Euclidean plane geometry two points defines exactly one line. On a sphere two points can define infinitely many lines only one of which will represent the shortest distance between the points. On other curved surfaces, or in non-Euclidean geometries, the number of lines determined by two points can vary. Even in the Euclidean plane, two points determine infinitely many lines that are not straight!
