**Dependent Variable**

A variable that depends on one or more other variables. For equations such as *y* = 3*x* – 2, the dependent variable is *y*. The value of *y* depends on the value chosen for *x*. Usually the dependent variable is isolated on one side of an equation. Formally, a dependent variable is a variable in an expression, equation, or function that has its value determined by the choice of value(s) of other variable(s).
