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 yaxis (positive
direction) and is one line above the xaxis (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 xcoordinate of 3 and a ycoordinate of
1.
