Subject: Re: Graphing linear inequalities

I have an opinion on this, although there may be some dispute. :-)

Graphing is a way to represent a phenomenon. If the graph properly allows people 
to realize what is occurring, or what phenomenon is represented, then it is 
appropriate. 

I guess the question I would ask anyone who "takes points off" of any graph is: 
"Did you understand what was being represented" or possibly more properly, would 
someone who understands about inequalities understand what was being represented? 

Good luck!

Rick
