Each point in a coordinate plane can be named by an ordered pair. The 1st coordinate, usually called the x- coordinate, tells how far left or right of the y-axis the point is located. The 2nd coordinate, usually called the y- coordinate, tells how far left or right of the y-axis the point is located.
