How do you explain coordinates?

Answer 1

co-ordinates are very simple to answer you graph like so:

you look at the numbers and the dots and bobs your uncle

Answer 2

Coordinates are pairs of numbers used to specify the precise location of a point in a space, such as a grid or map. In a two-dimensional coordinate system, like the Cartesian plane, the coordinates consist of an x-value (horizontal) and a y-value (vertical). In a three-dimensional system, a z-value is added to represent depth.
