| Direct Variation | Two variables x and y show this provided y = kx where k is a nonzero constant. |
| Function | A relation with exactly one output for each input. |
| Linear Function | A function of the form y = mx + b where m and b are constants and the graph forms a line. |
| Ordered Pair | A pair of numbers of the form (x, y) that represents a point in the coordinate plane. |
| Piecewise Function | A function represented by a combination of equations, each corresponding to a part of the domain. |
| Relation | A mapping , or pairing, of input values with output values. |
| Scatter Plot | A graph of ordered pairs used to determine whether there is a relationship between paired data. |
| Slope | The ratio of vertical change (rise) to horizontal change (run) for a nonvertical line. |
| Slope-Intercept Form | A linear equation written in the form y = mx + b where m is the slope and b is the y-intercept of the line. |
| Standard Form | A linear equation written in the form Ax + By = C where A and B are not both zero. |
