| Question | Answer |
|---|---|
| ordered pair | a pair of numbers that can be used to locate a point on a coordinate plane. |
| coordinate plane | a plane formed by the intersection of a horizontal number line called the x-axis and a vertical number line called the y-axis. |
| x-axis | the horizontal axis on a coordinate plane |
| y-axis | the vertical axis on a coordinate plane |
| x-coordinate | the first number in an ordered pair |
| y-coordinate | the second number in an ordered pair |
| origin | the intersection of the x-axis and y-axis. The point (0,0) |
| graph of an equation | the set of all ordered pairs that are solutions of the equation |
| function | a rule that relates two quantities so that each input value corresponds to exactly one output value. |
| input | the value substituted into an expression or function |
| output | the value that results from the substitution of a given input into a function |
| domain | the set of all possible input values |
| range | the set of all possible output values |
| vertical line test | A test used to tell if a graph is a function. If a vertical line intersects the graph at only one point, then the relationship is a function. |
| sequence | an ordered list of numbers or objects |
| term | an element or number is a sequence |
| arithmetic sequence | an ordered list of numbers in which the difference between consecutive terms is always the same |
| common difference | the difference between nay two successive terms in an arithmetic sequence |
