A set of infinitely many points extending endlessly in two opposite directions?

A set of infinitely many points extending endlessly in two opposite directions describes a line in geometry. This line can be represented mathematically as a one-dimensional space, where each point corresponds to a unique real number. It has no endpoints, meaning it continues infinitely in both directions, typically denoted using arrows on either end of the line segment. This concept is foundational in understanding linear equations and geometric principles.
