In this lecture, you'll learn how to solve systems of inequalities by graphing including systems that have no solution. Graphically, the solutions of the inequalities in such system have no intersection. As for solving systems of inequalities by graphing, we need to graph the solution set of each inequality. The solution of the system is the intersection of the solution sets of the inequalities. The way to find the solution set of an inequality was discussed in some of the previous lectures, but you'll get to revise that again. Jumping forward, you need to use the corresponding linear equations and a test point.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
