Systems of Inequalities
Use the sliders and check boxes to change the inequalities. Drag the point around to see when it is or is not a solution to the system of inequalities.
1. Graph the system of inequalities below[br][math]y < 2x + 1[/math][br][math]y ≥ -3x - 4.[/math][br][br]a. Is (1,6) a solution to the system of inequalities?[br]b. Change the inequality signs so the the point (-5, -2) is a solution to the system of inequalities.[br][br]2. Find a system of inequalities where (2, 0) is a solution. Use [math]>[/math] in one inequality and [math]≤[/math] in the other.
