Graphing Linear Inequalities: Where do I shade? ... MathWOEs

Four worked-out examples demonstrating two techniques (primarily using logic) for determining where the shading goes, when graphing a linear inequality.

The first technique is the "test point" method, which is explained here, but only shown once. The "logic" method is preferable because you don't need to use any arithmetic or pick any points, you just think about the direction of the y axis (or x axis).

(Recorded on a laptop's webcam, thus the soft focus.)
