That type of line would be called a ray.
displacement
A line that goes on forever in both directions is a line. One that starts at one point and continues forever in the other direction is a ray, and one that has two definite ends is a line segment.
A ray.
a line segment
then it is not a line it is a ray. line go on and on without stopping in both directions.
A ray.
It is called a ray.
Ray - A ray is part of a line that has one endpoint. It continues in one direction without ending.

displacement
A ray has one endpoint and continues indefinitely in one direction.
It could be a displacement vector.
A ray in geometry is a line with a single endpoint and extends indefinitely in one specified direction.
a line. starting from one point and going on as long as it needs to go on. or it could go on forever. it needs a start and a finish...
Draw a line. Stop. At the end of the line, draw another line in a different direction. Stop. At the end of that line, draw a line heading back in the general direction of where you started. Stop. Draw a fourth line that connects to your starting point.
A ray is similar to a line, however, it only continues in one direction, whereas a line continues in both. It's basically a line with only one arrow.
