Graphing on the Coordinate Plane The Cartesian coordinate system provides an easy way to locate points on a plane, which is a two-dimensional surface. It consists of a coordinate grid separated by a horizontal number line called the x-axis and a vertical number line called the y-axis. The intersection of these number lines is called the origin. The coordinates of the origin are (0,0). The two axes divide the grid into four quadrants, numbered I to IV counterclockwise. Every point on the grid can be identified with two numbers called coordinates: The first number is the x-coordinate (or abscissa). The second number is the y-coordinate (or ordinate). An ordered pair is made up of an x-coordinate and a y-coordinate. The x-coordinate tells you how far left or right of the origin the point is. The y-coordinate tells you how far up or down from the origin the point is. Locating Points on the Coordinate Plane The coordinate for this point is (2,-4). The x-coordinate is 2. That means we move 2 to the positive side of the origin. The y-coordinate is 4. That means we move 4 down from the x-axis.
