| Coordinate Plane | A coordinate plane is formed by the intersection of a horizontal number line, usually called the x-axis and a vertical number line, usually called the y-axis.
🗑
|

| Y-axis | The vertical number line in a coordinate plane
🗑
|

| X-coordinate | The first coordinate in an ordered pair, which indicates how many units to move to the left or right from the orgin
🗑
|
||||
| Y-coordinate | The second coordinate in an ordered pair, which indicates how many units to move up or down from the orgin
