there are 6 lines can pass through 4 noncollinear points.
Only one line can be drawn through eight points.
An infinite number of lines can be drawn through a single point, but only one through two points (of course, if the points don't have the same coordinates).
Since the question does not require them to be straight lines, the answer is infinitely many.
If you're talking about straight lines (not curves) the answer is one.

Only one line can be drawn through eight points.
In Euclidian or plane geometry, there can be only one line through two fixed points. Lines cannot actually be drawn; if you see it it is not a geometric line. If the points are on a curved surface as in a geometry that is non-Euclidian, then there can be infinitely many lines connecting two points.

1 straight line. An infinite number of curved lines.
