| the distance from 0 that an integer is on a number line | absolute value |
| opposite numbers that have a sum of 0 | additive inverse |
| two number lines that form a perpendicular intersection and create a coordinate plane | axes |
| the singular form of axes; usually the x and y... | axis |
| formed when two axes intersect; the point of intersection is 0 on each number line | coordinate plane |
| ordered pairs that give the x and y location of a point in on a plane | coordinates |
| the set of whole numbers and their opposites | integer |
| numbers that are less than 0 | negative numbers |
| numbers that are the same distance from 0. | opposites |
| the point where the axes of a coordinate plane intersect (0,0) | origin |
| numbers that are greater than 0 | positive numbers |
| one of the four sections or areas created in a coordinate plane. | quadrants |
| the horizontal axis of a coordinate plane | x-axis |
| the first number in ordered pair; shows the x-axis value of a point | x-coordinate |
| the vertical axis of a coordinate plane | y-axis |
| the second number in an ordered pair; shows the y-axis value of a point | y-coordinate |
