In this lesson I will teach you about the standard form of a linear equation.  If you recall y=mx + b is the general form of a line when it’s in slope-intercept form.  When a line is in standard form it’s general form will be Ax + By = C.  The main benefit of having a line in standard form is you can easily graph it using the x-y intercepts.  In the lesson I will also discuss how to convert a line from y=mx + b form into Ax + By = C standard form.   As you learn more about lines and there equations it’s easy to get confused so make sure you take good notes and review/practice as much as you can.
