Coordinate (Cartesian) Planes (Jump to: Lecture | Video )

Below is a Coordinate Plane:

Figure 1.

This two dimensional coordinate plane displays points on two dimensions: x, and y. Any point on this plane will have an x value, and a y value. The point in the very center of the plane is (0, 0).

Figure 2.

A red point has been plotted on the plane above. Where is the point located? Points are described in the format (x, y). So, this point is located at (5, 4).
