Graph a linear function: a step by step tutorial with examples and detailed solutions. Free graph paper is available.

Linear FunctionsAny function of the form f (x) = m x + b, where m is not equal to 0 is called a linear function. The domain of this function is the set of all real numbers. The range of f is the set of all real numbers. The graph of f is a line with slope m and y intercept b.Note: A function f (x) = b, where b is a constant real number is called a constant function. Its graph is a horizontal line at y = b.
