|---|---|
| absolute value | the distance of an integer from zero on a number line |
| coordinate plane | a plane formed by a horizontal line called the x-axis and a vertical line called the y-axis |
| integers | the set of whole numbers and their opposites |
| opposites | two numbers that are the same distance, but in opposite directions, from zero on a number line |
| ordered pair | a pair of numbers used to locate a point on a grid |
| origin | the point where the two axes of a coordinate plane intersect; (0, 0) |
| quadrants | the four regions of the coordinate plane separated by the x- and y-axes |
| rational number | any number that can be written as a ratio a/b where a and b are integers and b does not equal 0 |
| line of symmetry | a line that divides a figure into two halves that are reflections of each other |
| line symmetry | when a figure can be folded about a line so that its two parts match exactly |
| negative integer | any integer less than zero |
| positive integer | any integer greater than zero |
| x-axis | the horizontal line on a coordinate plane |
| x-coordinate | the first number in an ordered pair; tells the distance to move right or left from (0, 0) |
| y-axis | the vertical number line on a coordinate plane |
| y-coordinate | the second number in an ordered pair; tells the distance to move up or down from (0, 0) |
