The document discusses the coordinate plane and how to plot points on it. It defines key terms like axes, quadrants, and ordered pairs. The coordinate plane uses perpendicular x and y axes to locate all points, with the origin at their intersection. Ordered pairs (x,y) indicate points by listing the x-coordinate first, followed by the y-coordinate.
