it is simply called a line
A straight line of infinite length!
A set of points that form a straight path extending indefinitely in opposite directions is called a line. In geometry, a line is defined by two points through which it passes and can be represented by a linear equation in a coordinate system. Unlike line segments, which have defined endpoints, a line continues infinitely without any boundaries.

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 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.
