Question

How many point are contained in a line

Answer 1

If you are talk about a line segment, it would contain two points.

If your talking about a ray, it would contain 1 point.

If your talking about just the line, it would contain no points.

Answer 2

A line has infinite length, that is when produced in both direction ,there is no end.It has negligible thickness.

⇒If you put ,a point on a line and produce it in other direction we will call it ray.

⇒If you will put two points on a line,we will call it line segment.

⇒Two determine a unique line we need only two points.

⇒There are infinite number of Points on a line.We can prove this ,with the help of the following Statement.

⇒Between any two real numbers ,there are infinite number of real numbers.So, there are infinite number of points on the line.
