Doug Simms who runs a page at free math tutoring shows in this video a very broken down process that can help you understand how to graph a straight line from an algebraic equation and why it is that way. On a smart projecting board, in a slide show creating software, he explains at a steady pace how to break down a line into its individual line intercepts and an extra point thrown in for verification. After that, he takes the points and puts them on a graph to show you how to. You'll just have to ignore the giant, non-opaque watermark that he has left in the center of the video.
