Comment:  A pretty welldone and clean graphing calculator, but still I would prefer to use a graphing calculator.

Comment:  A cool way to introduce parallel, perpendicular, intersecting and coinciding lines. A good tool to visually teach the graphs of systems of equations. I am still looking for an interactive tool to graph from standard form.
