Khan Academy: Algebra: Graphing Linear Inequalities in Two Variables 2

Solving problems about pen and paper with systems of equations ... or is it the other way around? In the lesson, learners first interpret expressions and use equations in two variables to solve problems about notebooks and pens. They...

A set of example problems and exercises on linear inequalities in two variables. Includes how to write them using a graph or a table of values.

Although graphing a linear inequality on the plane is but a few steps added onto the graphing of a linear equation, for many learners the logical leap is quite intimidating. This approachable PowerPoint presentation breaks graphing...

This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is...

How can one equation have more than one solution? Well, if it has two variables, the solutions can be endless! Individuals explore the concept using a video tutorial that demonstrates finding multiple solutions to a linear equation in...

This video demonstrates how to write a two variable inequality given the graph of the inequality on a coordinate plane. Practice problems available. [3:20]

Mathematically complete a set of blueprints. Using eight linear inequalities, pupils create a blueprint of Thomas Jefferson's home. Individuals graph the linear inequalities and position the solution of the inequalities before...

Take the tediousness out of finding solutions of inequalities by graphing. Individuals use an interactive that allows them to adjust a system of inequalities on a coordinate plane. Using the interactive helps find solutions to systems of...

Graph and solve linear equations in two variables. The class relates the concepts of linear equations to the real world.

How many different ways can three planes intersect? The interactive provides three movable planes. Pupils manipulate the planes to determine the number of solutions possible based upon their intersections.
