13. An ordered pair gives the location of a point on a coordinate plane. The first number tells how far to move right (positive) or left (negative) from the origin. The second number tells how far to move up (positive) or down (negative). The numbers in an ordered pair are called coordinates . The first number is called the x -coordinate . The second number is called the y -coordinate . The ordered pair for the origin is (0,0).
