If we understand what you mean when you say "straight", then you could be describing a "line". -- But if it ever stops in one direction, then it's actually a "ray". -- And if it eventually stops in both directions, then it was a "line segment" all the time.
A straight line of infinite length!
Line
It is called a line. LOL
straight line
A line is a straight path that extends infinitely or endlessly in opposite directions. A straight path that joins two points is called a line segment.
Points do not extend, lines do.

A straight line.
line
It is an collection of an infinite number of points.
A line.
There are infinitely many points on a line, as a line extends endlessly in both directions. Each point on a line can be uniquely identified by its position on the line using the coordinates of the point.
