Graphic inequalities 2D
--- Introduction ---
The inequalities have a geometrical meaning: for example one
or several inequalities on two variables x and y describe a region
in the cartesian plane.
This online exercise helps you to establish the link between
the inequalities and plane regions. It can either plot a region and ask you
to recognize the corresponding inequality among a list to choose from,
or give an inequality and ask you to recognize the plane region it describes.
