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.
