Inequalities in one and two variables

A sheet where students have to shade the region of points satisfied by inequalities, and then work out what the inequalities are. I've attached the notebook file that I made all of the grids in so you can adapt if you wish. This also contains the answers for the sheet, and some questions where students shade the region for inequalities in two variables. Suitable for high ability KS3 (top set y9) and KS4.
