Sometimes the best way to solve an equation, a system of equations, or a system of inequalities is to look at a graph of the equation or the system. Finding solutions on graphs is different from using algebraic properties to solve for a variable, but it gives the same results. For each of the three graphs, describe how and why the graph shows the solutions of the equation or system of equations or inequalities.
