|---|---|
| algebra | a branch of mathematics dealing with symbols |
| algebraic expression | an expression that contains sums and/or products of variables and numbers |

| graph | a dot at the point that corresponds to an ordered pair on a coordinate plane |
| inductive reasoning | conjecture based on a pattern of examples or past events |
| numerical expression | a combination of numbers and operations such as addition, subtraction, multiplication and division |
| open sentence | an equation that contains a variable |
| order of operations | PEMDAS |
| ordered pair | a pair of numbers used to locate any point on a coordinate plane |
| origin | the point at which the number lines intersect in a coordinate system |
| properties | statements of equality of two or more ratios |
| range | all the y-coordinates from each ordered pairs in a relation |
| relation | a set of ordered pairs |
| scatter plot | a graph that shows the relationship between two sets of data |
| simplify | to write an expression in simpler form |
| solution | a value for the variable that makes an equation true |
| solving the equation | the process of finding a solution to an equation |
