- 3. A combination of symbols and terms that look like an equation but are missing an equals sign.
- 6. The number of square units required to cover a surface. Length times width

- 12. To replace a variable with a number.
- 16. A place where two lines on a graph meet.
- 18. A number that measures its "steepness", usually denoted by the letter m. It is the change in y for a unit change in x along the line. Also called rise over run.
- 19. A relationship or expression involving one or more variables, where each x value (the input) has only one y value (the output). Passes the verticle line test

- 9. One is the same as the other.
- 10. Two ratios that are equal to each other.
- 11. An approximation or a rounding of a number.
