The document describes key concepts about the coordinate plane:
- The coordinate plane contains perpendicular x and y axes that intersect at the origin (0,0).
- Points on the plane are located using ordered pairs (x,y) where x is the distance from the y-axis and y is the distance from the x-axis.
- The plane is divided into four quadrants based on whether x and y are positive or negative.
- Examples show how to graph points, identify quadrants, and understand properties of the axes.
