A Ray.
A line extends infinitely in both directions, while a ray has a starting point and extends infinitely in one direction. A line has no endpoints, while a ray has one endpoint.

False
A line is related to a surface as a point to a plane. In geometry, a point has no dimensions and defines a location in space, while a plane is a two-dimensional surface that extends infinitely in all directions. Similarly, a line is a one-dimensional figure that extends infinitely in two opposite directions, while a surface is a two-dimensional figure that extends infinitely in all directions.
Two. If it were more than two it wouldn't be a line.
Hopefully the same thing it means in most other grades of geometry, which is a straight one dimensional object that is infinitely long. It differs from a ray, which has a finite point and extends infinitely from that point in a single direction, and a line segment, which has two finite ends.
The point at the beginning of a ray is called the "endpoint." A ray is a part of a line that starts at this endpoint and extends infinitely in one direction. The endpoint is crucial as it defines where the ray begins, distinguishing it from a line segment, which has two endpoints.
A ray starts at a point and extends forever in ONE direction. A line starts at a point and extends forever in TWO directions.
a half-line with a designated end point which extends in only one direction without stopping
