Students will write an equation in slope-intercept form given two points on the line; write an equation in Ax + By = C form given slope and one set of coordinates; and prove lines to be parallel or perpendicular given vertices of...

Dr. Math discusses the usefulness of standard form of linear equations on this page. The Dr. discusses parallel and perpendicular lines as well as graphing techniques. The Dr. touches on what the canonical form is and its usefulness.

Review the key concepts and skills for inclined planes, including how to write Newton's second law for forces parallel and perpendicular to the incline.

This lesson on slope explains the slope concepts, demonstrates how to use the slope formula, shows how to find slope in horizontal and vertical lines, and how to use slope to find whether the lines through the pairs of points are...
