The Coordinate Plane Objective: Graph points on a coordinate plane.

A coordinate plane is formed when two number lines intersect. The number lines separate the coordinate plane into four regions called quadrant. An ordered pair of numbers, such as (3, -2), used to locate a point in the coordinate plane. X-coordinate corresponds to a number on the X- axis. Y-coordinate corresponds to a number on the Y-axis. The origin is at (0,0).

When locating an ordered pair, moving right and up on a coordinate plane is in the positive direction. Moving left and down is in the negative direction. Steps to graph an ordered pair: 1. Start at the origin. 2. Move left or right on the X- axis to find the X-coordinate.. 3. Then moveup or down to find the Y-coordinate.
