Drag points A, B, C, and D to move the lines to graph the equations given. The lines will turn green when they are correct. (You may need to use the zoom in and zoom out tools located under the Move Graphics View tool in the toolbar.)
Then state the solution to the system of equations, which will either be the point where the lines intersect, no solution, or infinitely many solutions.
Once you get the correct solution move the slider to go to the next problem.
