coordinates
The two numbers, written (x,y), that pin down one exact point on a graph.
A point's coordinates are an ordered pair (x,y), where x says how far right (or left, if negative) of the origin, and y says how far up (or down) from it. The order matters — (2,5) and (5,2) are different points.
Examples
The point with coordinates (3,-2) sits 3 units right and 2 units down from the origin.
