In this video, I discuss how to determine the set of points which satisfies a system of two linear inequalities. I begin by deriving the solution set for a system of linear inequalities where the corresponding lines intersect, then I go on to derive the solution set for the system of inequalities with parallel lines.

I'd like to thank James Mark Wilson, one of my patrons, for providing the content and inspiration for this video! Also, as promised, here is the example problem and solution: drive.google.com/open?id=1ET6F5SunBbYZYWHiOk5lfS5HDvK1rU5Y

Questions/requests? Let me know in the comments!

Prerequisites: Basic Grade 8/9 algebra (i.e. knowledge of lines, slopes, linear systems of 2 equations).
