coorinate pair an ordered pair of numbers used to locate a point on a coordinate grid. The first number in a coordinate pair is the value for the x-coordinate, and the second number is the value for the y-coordinate. A coordinate pair for the graph shown above is (0,60)
dependent variable one of the two variables in a relationship. Its value depends upon or is determined by the other variable called the independent variable. For example, the cost on how long you talk (independent variable).
equation,formula a rule containing variables that represents a mathmatical relationship. An example is the formula for finding the area of a circle:A=JTr2.

independent variable one of the two variables in a relationship. Its value determines the value of the other variable called the dependent value. If you organize a bike tour, for example, the number of people who register togo (independent variable).
