THE COORDINATE PLANE

Coordinate Plane Formed by the intersection of two number lines

Parts of the Coordinate Plane x-axis: the horizontal number line y-axis: the vertical number line Quadrants: the 4 areas the coordinate plane is divided into Written as Roman numerals Origin: the intersection point of the number lines; (0, 0)

Ordered Pair Gives the location of a point as coordinates in (x, y) format **order DOES count
