| A | B |
|---|
| associative property | the way you group does not change the outcome (a+b) + c = a + (b + c) |
| commutative property | the order does not change the outcome a + b = b + a, a x b = b x a |
| direct variation | the relationship of two variables, x and y, if there is a nonzero number such that y = ax. When you solve for a, this becomes a = y/x |
| domain of a function | the set of all i nfuts of a function |
| inverse variation | the relationship of two variables, x and y, if there is a nonzero number such that y = a/x. When you solve for a, this becomes a = xy |
| range of a function | the set of all outputs of a function |
| reflexive property | anything is equal to itself, a = a |
| slope | the slope m of a nonvertical line is the ratio of the vertical change (the risr) to the horizontal change (the run) between the points (x1, y1) and (x2, y2) on the same line m = y2-y1/x2-x1 |
| slope-intetrcept form | a linear equation written in the form y = mx+b, where m is the slope and b is the y-intercept of the equation's graph |
| standard form of a linear equation | Ax + By = C, where A, B, and C are real numbers and A and B are not both zero. Additionally, A and B nust be integers and A must be positive |
| symmetric property | if two things are equal, it doesn't matter which one you write first. If a = b, then b = a. |
| transitive property | iIf two things are equal to the same thing, they are equal to each other. If a = b and b = c, then a = c. |
