That's the definition of a "line".

It is often called a straight-edge.

A line
The term you are describing is a line.
A straight line is a geometric concept that extends infinitely in both directions without any endpoints. It is defined by its linearity and uniformity, maintaining a constant direction throughout its length. In mathematics, straight lines are often represented in equations and graphs, illustrating their endless nature.
A straight line with no endpoints is a geometric concept that extends infinitely in both directions. It is often represented in mathematics by a line symbol, denoted by two points on the line or with a single letter. Unlike line segments, which have defined starting and ending points, a straight line has an infinite length and continues indefinitely without termination.

A line.
A ray has one endpoint and extends infinitely in one direction. The endpoint is where the ray begins, while the opposite side continues without bound. This distinguishes a ray from a line segment, which has two endpoints, and a line, which has no endpoints.
line
A ray has one endpoint and extends infinitely in one direction. It consists of all points along a straight line starting from the endpoint and continuing without end. Therefore, it does not have an infinite number of endpoints; it has only one.
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.
A straight line that touches a curve but continues without crossing it is called a "tangent." At the point of contact, the tangent line has the same slope as the curve, indicating that it just grazes the curve rather than intersecting it.
If you meant one direction, then it is a ray.
