Writing Equations of Lines Parallel and Perpendicular to a Given Line Through a Point

This algebra video tutorial shows you how to write the equation of a line that is parallel and perpendicular to a given that passes through a point. This video shows you how to do it using the slope intercept form of the equation and the point slope form. It also shows you how to take the negative reciprocal of the slope of the given line to find the slope of the perpendicular line. This video contains plenty of examples and practice problems for you to work on.
