| absolute value | A number’s distance from 0 on the number line. Absolute value is never negative. |
| Coordinate plane | A two-dimensional space formed by two perpendicular number lines called axes. |
| integers | The set of whole numbers and their opposites. |
| inequality | A mathematical statement that uses an inequality symbol (<, >, , ) to show the relationship between values of expressions. |
| Negative numbers | Numbers that are less than 0. They are located to the left of 0 on a horizontal number line and below 0 on a vertical number line. |
| Ordered pair | A pair of numbers, (x,y), that describes the location of a point in the coordinate |
| Positive numbers | Numbers that are greater than 0. They are located to the right of 0 on a horizontal number line and above 0 on a vertical number line. |
| quadrants | The four regions of the coordinate plane that are formed when the x-axis and y-axis intersect at the origin. |
| Rational number | A number that can be expressed as the fraction abor the opposite of ab where a and b are whole numbers and b0. Rational numbers can also be expressed as a decimal. |
| reflection | When a figure is flipped (reflected) across a line to form a mirror image. |
| Whole numbers | The numbers 0, 1, 2, 3, 4… whole numbers are nonnegative and have no fractional part. |
| x-axis | The horizontal number line in the coordinate plane. |
| y-axis | The vertical number line in the coordinate plane. |
| x-coordinate | The first number in an ordered pair. It tells the point’s horizontal distance from the y-axis. |
| y-coordinate | The second number in an ordered pair. It tells the point’s vertical distance from the x-axis. |
