Coordinates-
Definition-
The number matching to a point on the number line or an ordered pair (x,y). On maps and graphs it is frequent to have a set of numbers to show where a point is. The first number shows the space along and the second number shows the space up or down.
Example-
(x,y) So x comes first on the graph so if your coordinates are (14,6) then you would go 14 units along, and 6 units up.
