it is called a ray
a straight line that extends for a point forever in one direction
a line a ray goes in only one direction forever No, a line goes on forever in two directions, a ray starts at one point and then goes on forever.
A line segment is a straight line that has endpoints.
Yes, because a ray is a line with an end point. It goes on forever in one direction.
It's true, it's in the book

If you are talking about line segment-type objects, it would be a ray.
If you mean a straight path, rather than a strait path, then it is a ray.
a line a ray goes in only one direction forever No, a line goes on forever in two directions, a ray starts at one point and then goes on forever.
A ray is a straight line that starts at a point and extends infinitely in one direction. It has a defined endpoint but continues on forever in the direction it points. A ray can be represented with an arrow pointing in the direction of its extension.
A ray starts at a point and extends forever in ONE direction. A line starts at a point and extends forever in TWO directions.
displacement
A ray starts at a point and extends forever in ONE direction. A line starts at a point and extends forever in TWO directions.
Stand straight. Now point straight up. Point straight ahead. Point straight to your left. Now point in a direction at right angles with all three previous directions: there's your extra dimension.
It could be a displacement vector.
