| Corresponding Parts | Angles that are in the same position on two parallel lines in relation to a transversal |
| Direct Variation | A relationship between two variables quantities with a constant ratio, a proportional linear relationship |
| Initial Value | The starting value in a real world situation in which an equation can be written, the Y-Intercept of a linear function |
