In this lecture Professor Fraser will teach you Graphing Inequalities. You will begin with Graphing Linear Inequalities and learn important aspects such as the Half Plane and utilizing a Test Point. Then you will graduate to Graphing Absolute Value Inequalities. You will cement your knowledge with several examples.
The graph of a
linear inequality is a half plane bounded by a straight line.
If the inequality
is strict (< or >), then draw the boundary as a dashed line,
otherwise draw it as a solid line.
Use a test point,
normally the origin, to determine which half plane is the solution
of the inequality. Shade that region.
Lecture Slides are screen-captured images of important points in the lecture. Students can download and print out these lecture slide images to do practice problems as well as take notes while watching the lecture.
