| Once you have determined the co-ordinates of a point, you can label the points using ordered pair notation. |
| The holes centres in parts are determined in a plane, in a two-dimensional space by an ordered pair of real numbers. |
| Functions can be defined by the ordered pair notation, tables, or graphs. |
| A simple illustration of explication is provided by the definition of ordered pair in set theory. |
| In linear algebra, an ordered pair of numbers typically represents a vector, which in the present setting of coordinates can be taken to mean a change in location. |
