This particular video, while I think one of my best, still has a minor mistake that is corrected in the updated version. Just click the caption in the video to get to it. This video demonstrates how to graph linear inequalities in standard form with the x- and y-terms on one side of the symbol and the number on the other side of the inequality. This method involves finding the x- and y-intercepts, then drawing a line through the two intercepts, forming a boundary line. Whether the boundary line is dashed or solid is discussed. Also, which way to shade the inequality, above or below the boundary line is covered. Another thing covered is if you have to change the direction of the inequality symbol when dividing by a negative number to solve for y. Finally, checking the proper shading by using the point (0, 0) is demonstrated.
