What is a Linear Function? How to Solve a Linear Function?

If you’ve previously learned how to solve linear equations, you’re ready to move onto solving linear functions. They’re very similar, and the process also uses easy steps, so if you’re solving linear equations in your sleep, functions will be a breeze!

Step 1: Determine that you are, in fact, looking at a linear function.

In case you didn’t already know, a linear function will always begin with f(x) =, followed by the rest of the equation. It’s easy enough to remember, since the f stands for function. A linear function often closely follows the slope intercept formula you learned earlier in Algebra, which is y = mx + b. Step 2: Substitute variables for values as instructed.

When you’re first introduced to linear functions, you’ll most likely be given a value to substitute for your variable. Other functions will ask you to find the equation of a line, and then solve the corresponding function. In either case, substitute the values you’re given to solve for your variable.
