In algebra a linear equation is one that contains two variables and can be plotted on a graph as a straight line. Key common points of linear parent functions include the fact that the: Equation is y = x. Domain and range are real numbers. Slope or rate of change is constant.

A linear parent function is the equation y = x or f(x) = x. A parent function is the simplest equation of a function. Thus f(x) = x is the simplest of all linear functions and that is the reason why it is called linear parent function.
