This pdf includes x,y coordinate, ordered pair, and quadrants. A Cartesian coordinate system in a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length.
1. Notes Coordinate Plane Coordinate Plane - The plane determined by two perpendicular axes. Coordinate (Cartesian) Plane Coordinates - Each point in the coordinate plane corresponds to an ordered pair of numbers called its coordinates. X-Coordinate - The first coordinate in an ordered pair. This represents the independent variable. Y-Coordinate - The second coordinate in an ordered pair. This represents the dependent variable. Ordered Pair - A set of two numbers, with the x-coordinate (independent variable) listed first, and the y-coordinate (dependent variable) listed second. Quadrants - The x-axis and y-axis separate the plane into four regions called quadrants. They are numbered with Roman numerals, beginning in the upper right quadrant and proceeding in a counter-clockwise rotation.
