Shading the other side of an equality (2D)
I am teaching Linear Programming (in two variables) and our custom is to create a feasible region by shading out the area which is outside the feasible region. Most packages seem to shade inside as does GeoGebra. For example y>x on GeoGebra shades above the diagonal line (excluding the line) but I would like to shade below the line.
This is for year 13 students who are not that confident with Algebra so asking them to simply invert the inequality won't cut it. Is there a setting you can use to switch the shading?
At the moment, we are using Autograph V3.3 which shades as required by default but its not a great application. A browser based solution would be much better.
