| coordinate plane | A plane in which a horizontal number line and a vertical number line intersect at their zero points. |
| equivalent ratio | Ratios that express the same relationship between two quantities. |
| graph | To place a dot at a point named by an ordered pair. |
| greatest common factor | The greatest of the common factors of two or more numbers. |
| least common multiple | The smallest whole number greater than 0 that is a common multiple of each of two or more numbers. |
| ordered pair | A pair of numbers used to locate a point on the coordinate plane. The ordered pair is written in the form (x-coordinate, y-coordinate) |
| origin | The point of intersection of the x-axis and y-axis on a coordinate plane. |
| rate | A ratio comparing two quantities with different kinds of units |
| ratio | A comparison of two quantities by division. The ratio of 2 to 3 can be stated as 2 out of 3, 2 to 3, 2:3 or 2/3 |
| ratio table | A table with columns filled with pairs of numbers that have the same ratio |
| scaling | To multiply or divide two related quantities by the same number. |
| unit price | The cost per unit. |
| unit rate | A rate that is simplified so that it has a denominator of 1 |
| x-axis | The horizontal line of the two perpendicular number lines in a coordinate plane. |
| x-coordinate | The first number of an ordered pair. The x-coordinate corresponds to a number on the x-axis |
| y-axis | The vertical line of the two perpendicular number lines in a coordinate plane. |
| y-coordinate | The second number of an ordered pair. The y-coordinate corresponds to a number on the y-axis. |
