| A | B |
|---|
| axes | 2 perpendicular #lines that intersect |
| origin | point that corresponds to the # 0 |
| x-axis | horizontal axis |
| y-axis | vertical axis |
| coordinate axes | x and y axis on a coord. plane |
| coordinate plane | plane on which a coordinate system is set up |
| quadrants | 1 of 4 regions into which a plane is sep. |
| coordinate | can be assigned to a pair of real #'s |
| abscissa | 1st coord. of an ordered pair of real #'s |
| x-coordinate | coord. of a point where line intersects the x-axis |
| y-coordinate | coordinate of a point where line intersects the y axis |
| ordinate | 2nd coord. of ordered pair |
| ordered pair | a pair of #'s, order is important |
| graph of ordered pair | point that corresponds to the ordered pair on a coord. plane |
| plot of point | finding the point that corresponds to an ordered pair |
