Terms | Definitions |
|---|---|
 Absolute value | The distance between a number and zero on the number line. The symbol for absolute value is shown in the equation |-8| = 8. |
| Coordinates | An ordered pair, (x, y) that locates a point in a plane. |
| Inequality | Any mathematical sentence that contains the symbols > (greater than), < (less than), ≤ (less than or equal to), or ≥ (greater than or equal to). |
| Integers | The set of whole numbers and their opposites (..., -3, -2, -1, 0, 1, 2, 3, ...) |
| Negative numbers | The set of numbers less than zero. |
| Opposite number | Two different numbers that have the same absolute value. Example: 4 and -4 are opposite numbers because both have an absolute value of 4. |
| Ordered Pair | A pair of numbers, (x, y), that indicates the position of a point on the Cartesian Plane. |
| Origin | The point of intersection of the vertical and horizontal axes of a Cartesian plane. The coordinates of the origin are (0, 0). |
| Positive Number | The set of numbers greater than zero. |
| Rational Number | The set of numbers that can be written in the form a/b where a and b are integers and b is not 0. |
| Sign | A symbol that indicates whether a number is positive or negative. Example: In -4, the (-) sign indicates how this number is read "negative four." |
| x-axis | The horizontal number line on the Cartesian coordinate plane. |
| x-coordinate | The first number of an ordered pair; the position of a point relative to the vertical axis. |
| y-axis | The vertical number line on the Cartesian coordinate plane. |
| y-coordinate | The second number of an ordered pair; the position of a point relative to the horizontal axis. |
