**Additional Resources:**Most of Khan Academy's offerings on linear equations and inequalities are more introductory than you will need. However, the last eight of them give some examples and illustrations that you may find helpful. And if you're rusty on the basics of plotting points or graphing straight lines, some of the earlier videos in this collection may be useful to you. Feel free to browse.
