| rule | A procedure that a count must follow |
| plot | Placing a point on a coordinate plane by using X and Y coordinates |
| vertical | A position or direction perpendicular to the plane of the horizon |
| coordinate plane | A plane containing two perpendicular axes (x and y) intersecting at a point called the origin |
| sequence | An ordered set of numbers arranged to a rule |
| corresponding terms | Appearing in identical places in two similar situations |
| axis, axes | Real or imaginary reference line |
| perpendicular | At an angle of 90° to a given line, plane, or surface |
| term | One of the numbers in a sequence |
| x-axis | The horizontal axis of a graph |
| coordinates | Shown as pairs of numbers; Used to show position on a coordinate plane |
| origin | The point of intersection of the x and y axis on a coordinate plane; The coordinates are (0,0) |
| y-coordinate | The position of a point according to the y-axis |
| point | An exact location or position on a coordinate plane |
| horizontal | Parallel to the horizon |
| x-coordinate | The position of a point according to the x-axis |
| ordered pair | A pair of numbers where order is important, for example, (4,6) is different than (6,4); Often used to indicate a point on a coordinate plane |
| y-axis | The vertical axis of a coordinate plane |
| parallel | Are the same distance apart; Never intersect |
