🗑
|
||||
| coordinate plane | a plane is formed by the intersection of a horizontal number line, usually called the x-axis, ans a vertical number line, usually called the y-axis.
🗑
|
||||
| x-axis | the horizontal number in a coordinate plane.
🗑
|
||||
| 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 origin.
🗑
|
||||
| y-coordinate | the second coordinate in an ordered pair, which indicates how many units to move up or down from the origin.
