Dr. Eaton begins Solving Systems of Inequalities by Graphing with a review of how to solve linear equations by graphing and then links it to inequalities. Steps include graphing the corresponding linear equations and then choosing test points. The possibility of no solutions is also covered and also known as the empty set. At the end of the lecture you will test your knowledge with four complete problems that will need to be solved by graphing.
To solve a system, graph each inequality. The solution of the system is the intersection of the graphs of the inequalities.
If the intersection is empty, the system has no solution.
