I have some great graphing problems in which students can be asked to graph lines and parabolas that use JSXGraph and are adapted from a problem from Glenn Rice.

But I have not created any yet for graphing linear inequalities of two variables.

Does anyone have any problems like this already? I'm looking for problems where the student selects whether the line should be solid or dashed, then picks two points on the line (on a grid) to graph the boundary line and finally indicates somehow which side should be shaded.

If none exist yet, I may create some this summer, but I don't have time to create them this spring in time to have my students use them.

Thanks!

Paul
