Two-variable linear inequalities

In this topic, we study inequalities like x+2y>5 and graph them. This helps us see their solutions. We also explore systems of inequalities (multiple inequalities at the same time) and use them to describe real-world situations.

Learn how to check possible solutions of two-variable linear inequalities. For example, is (2, 0) a solution to y>x+1? In this tutorial, we also check solutions to systems of inequalities.
