| independent variable | the variable in a function with a value that is subject to choice |
| dependent variable | the variable in a relation with a value that depends on the value of the independent variable |
| vertical line test | If any vertical line drawn on the graph of a relation passes through no more than one oint on the graph for each value of x in the domain, then the relation is a function. |
| function notation | a way to name a junction that is defined by an equation. Ex. (f)x = 3x - 8 |
| sequence | an ordered list of numbers |
| arithmetic sequence | when the difference between any two consecutive terms is the same |
| term | each number in a sequence |
| linear equation | an equation whose line is a graph |
| rate of change | a rate that describes how one quantity changes in relation to another quantity |
| linear relationship | a relationship that has a straight-line graph |
| constant rate of change | the rates of change between any two data points in a linear relationship are the same or contant |
| direct variation | a special type of linear equation that describes rate of change. A relationship such that as x increases in value, y increases ore decreases at a constant change. |
| slope | the ratio of the rise, or vertical change, to the run, or horizontal change of a line. It describes the steepness of a line. |
| slope-intercept form | an equation of the form y = mx + b, where m is slope and b is y-intercept |
