I'm not always sure how you know which way you need to shade on a graph and which part is the feasible region.


  1. Yeah I was confused on this too.

  2. You just have to pick a point and plug it into your equation to see if the point works. You can always use Mrs. Kerr's favorite (0,0) and if the coordinate point works then you shade the part the point falls into.
