 Description  
 Coordinates:  An ordered pair, (x,y), that locates a point in the plane.

Each point graphed can be represented by a unique pair of numbers called an ordered pair. The intersection of the two axes on a coordinate plane is called the origin and is represented by the ordered pair (0,0). The red dot is three lines to the right of the y-axis (positive direction) and is one line above the x-axis (positive direction). So the red dot is represented by the ordered pair (3,1). The numbers in the ordered pair are called the coordinates. The red point has an x-coordinate of 3 and a y-coordinate of 1.
