The Rectangular Coordinate Plane (2)
In the previous example, points A, B, and C are points on the x-axis. Observe that any point on the x-axis has a y-coordinate equal to 0.
On the other hand, points D, E, and G are points on the y-axis. You can say that any point on the y-axis has an x-coordinate equal to 0.
Lastly, point F is at the origin. It lies on the intersection of both axes and has 0 as its x- and y-coordinates.
In general, the following statements are true:
- Any point on the x-axis has coordinates of the form where a is a real number.
- Any point on the y-axis has coordinates of the form where b is a real number.
- The origin has coordinates
