A linear function is a function whose graph is a line. Thus, it is of the form f(x) = ax + b where 'a' and 'b' are real numbers. Learn how to find graph a linear function, what is its domain and range, and how to find its inverse?
Graphing Linear Functions. There are three basic methods of graphing linear functions. The first is by plotting points and then drawing a line through the points. The second is by using the \(y\)-intercept and slope. And the third is by using transformations of the identity function \(f(x)=x.\)
There are three basic methods of graphing linear functions. The first is by plotting points and then drawing a line through the points. The second is by using the y- intercept and slope. And the third is by using transformations of the identity function f\left (x\right)=x f (x) = x.
A linear function is a function whose graph is a line. Linear functions can be written in the slope-intercept form of a line \[f(x)=mx+b\] where \(b\) is the initial or starting value of the function (when input, \(x=0\)), and \(m\) is the constant rate of change, or slope of the function. The y-intercept is at \((0,b)\).

Given a linear function, graph by plotting points. Choose a minimum of two input values. Evaluate the function at each input value. Use the resulting output values to identify coordinate pairs. Plot the coordinate pairs on a grid. Draw a line through the points.

The graph of a linear equation is a visual representation of a linear function. There are several ways you can express linear equations and graph linear equations. Let’s focus on the slope intercept form of a linear equation which is defined as: y = mx + by = mx+b.
