The video lesson explores an example of how systems of linear inequalities can be applied in the real world.

Students learn to estimate the solution set, in real numbers, of a linear inequality using graphical methods on a number line and on a Cartesian (x-y) graph. They also learn how to solve inequalities using tables.

This site is a tutorial for students in algebra 2 or for those who need a refresher. The site has explanations, definitions, examples, practice problems and practice tests are found covering topics such as linear equations, graphing,...

This interactive Java applet allows the user to construct up to 5 linear inequalities and view the graph of the soultion.

Students study quadratic relationships and explore the process of graphing quadratic inequalities and systems of quadratic inequalities. They will solve these inequalities algebraically and graph them on a coordinate plane.

This college site offers a variety of problems and answers. Problems are divided into topic areas for easy access. Also offers quizzes with each topic.

Graph two-variable linear inequalities. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.
