Independent Variable
A variable in an equation that
may have its value freely chosen without considering values of
any
other
variable.
For equations such as y = 3x – 2,
the independent variable is x. The variable y is not independent since it depends
on the number chosen for x.
Formally, an independent variable
is a variable which can be assigned any permissible value without
any restriction imposed by any other variable.
