Only one line can be drawn through eight points.
One.
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.
If you're talking about straight lines (not curves) the answer is one.
uncountable lines can be drawn through one point.
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.
A line consists of infinitely many points which all satisfy some condition. In that respect, one point or even a trillion points do not make a line. There are infinitely many lines that can be drawn through one point.
If you are talking about straight lines, the answer is NONE, because that is what noncollinear means. If curves are allowed, then the answer is infinitely many.
There are 91 lines.
