 Cartesian Coordinates(Read the definition below of Cartesian plane first) Coordinates on the Cartesian plane are a set of numbers officially called "an ordered pair" that are in the form ( x , y ) ...  The x guy is how far to the right or left you've counted over... and the y guy is how far up or down you've counted.
