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.
