Independent Dependent Variable Relations Functions

What definition represents dependent variable?

• A linear

  relationship between two variables,

  x and y, that can be written in the form

  y = kx, where k is a nonzero cons

• The output

  of a function; a variable whose value

  depends on the value of the input, or

  independent variable.
