Graphing Linear Inequalities from Standard Form

http://www.gdawgenterprises.com

This particular video, while I think one of my best, still has a minor mistake that is corrected in the updated version. Just click the caption in the video to get to it. This video demonstrates how to graph linear inequalities in standard form with the x- and y-terms on one side of the symbol and the number on the other side of the inequality. This method involves finding the x- and y-intercepts, then drawing a line through the two intercepts, forming a boundary line. Whether the boundary line is dashed or solid is discussed. Also, which way to shade the inequality, above or below the boundary line is covered. Another thing covered is if you have to change the direction of the inequality symbol when dividing by a negative number to solve for y. Finally, checking the proper shading by using the point (0, 0) is demonstrated.

Is that "Lose Yourself" in the background?

@AnOmiCKs You are correct. I started using it before Chrysler but didn't pay as much to use it. Thanks for viewing and commenting.

5:43 he didnt switch the symbol

@mtvrdeich You are correct. I could have and technically should have. But the x-intercept was needed only to draw the boundary line. It was with the y-intercept that I used to determine the direction of the inequality and so in spite of my technical lapse, the inequality was still graphed correctly. Plus I used the checking procedure that would also have caught a mistake as well. Thanks for viewing and commenting.
