Rectangular Coordinate Plane

Additional Resources:

In this lesson, we review the rectangular coordinate plane, which is also known as the Cartesian coordinate plane or just the coordinate plane. We will discuss the general makeup of the coordinate plane. The coordinate plane is made up of two perpendicular number lines. The horizontal number line represents the x-axis and the vertical number line represents the y-axis. Additionally, we will discuss the quadrants of a coordinate plane, and how to graph points (ordered pairs) on the coordinate plane.
