Question

A line through two points $A$ and $B$ is written as _______

Answer 1

We know that,

A line is a one-dimensional figure, which has length but no width. A line is made of a set of points which is extended in opposite directions infinitely.

A line segment is bounded by two distinct points on a line. Or we can say a line segment is part of the line that connects two points.

Hence, a line through two points $A$ and $B$ is written as line segment.
