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\ge-3x-4[/math][br]Is (1,6) a solution to the system of inequalities?
2. Change the inequality signs on the system of inequalities from #1, so that the point (-5,-2) is a solution. Type this new system below.[br]
Find a system of inequalities where (2,0) is a solution. Use > in one inequality and [math]\le[/math] in the other.[br] Type this system below.
