(nonâ³linâ²Ä-Är) Not linear; not obeying a linear relationship. In mathematics, a linear equation may be given in the form y = mx + b, where x is the independent variable, and y is the dependent variable. A nonlinear relationship cannot be represented by such an equation.
1 Linear vs. nonlinear: If all the operators in a mathematical model exhibit linearity, the resulting mathematical model is defined as linear. 2  A model is considered to be nonlinear otherwise. 3  The definition of linearity and nonlinearity is dependent on context, and linear models may have nonlinear expressions in them.
