Linear equations can always be written in the form

When we graph such an equation, we can see why they are called "linear."  That is, the graph is a "straight line."

In this lesson you will learn how to identify the fundamental components of a given line by studying both its equation and its graph.

You will also learn how to use these components to build linear equations.
