Inequalities (systems & graphs)

Algebra I,

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.

This course contains 3 segments:

Checking solutions of two-variable inequalities

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.

Graphing two-variable inequalities

Learn how to graph two-variables linear inequalities and systems of two-variable linear inequalities.

Modeling with linear inequalities

Learn how to construct linear inequalities and systems of inequalities given a real-life context. Learn how to interpret such inequalities in terms of a real-life context, either algebraically or graphically.
