This course contains 4 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.

Constraining solutions of two-variable inequalities

Given a specific value for one of the variables in a two-variable linear inequality (or system of inequalities), learn how to find the corresponding range of values for the other variable. For example, given that x=3, what are the possible values for y in 2x+y<1 ?

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.
