  1. Origin X – Axis Y – Axis Cartesian Coordinate System Quadrants Ordered Pair Coordinates

  2. Terminologies: Cartesian Coordinate plane a two-dimensional surface on which a coordinate system has been set up; invented by Rene Descartes; also called Cartesian plane, graph, coordinate grid.

  3. Coordinates the numbers in an ordered pair that locate a point in the coordinate plane. Ordered pair a pair of numbers, written as (x, y), that represents a point on a coordinate grid.

  4. X-axis the horizontal number line on a coordinate grid. Y-axis the vertical number line on a coordinate grid

  5. Quadrants The four parts made by X and Y axis Origin Intersection of X and Y axis
