What is the minimum number of distinct points required to determine a unique line?

A line is defined as a straight path that extends infinitely in both directions. It can be represented by an equation or a graph.

To determine a unique line, we need at least two distinct points. Any two points in a plane can be connected by a unique straight line or a line segment. This gives a line a definition that is length.

If we have only one point, we cannot determine a line because there are infinitely many lines that pass through that point and have different slopes.

Therefore, a unique line is determined by two distinct points.
