Only one line can be drawn through eight points.
line segments
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.
uncountable lines can be drawn through one point.
In Geometry
1 straight line. An infinite number of curved lines.
If you're talking about straight lines (not curves) the answer is one.
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).
There is only one possible line that can can through two different points, presuming there are no overlaps.
There is only one possible line that can can through two different points, presuming there are no overlaps.
Infinite lines because a circle has infinite lines of symmetry.
Just one.
