Practice of Systems of Equations
Find the x- and y-intercepts for each graph then click "Draw Line". You will need to place the purple Intersection Point where the lines cross. The Intersection Point requires accuracy to two decimal places, so you may find it helpful to type coordinates of the Intersection Point into the box on the left hand side. Once both lines and intersection point are drawn, place the green dot in the region of the graph containing the solutions and click "Shade Solutions".
