**Graphing Systems of Equations**

Lesson 3-1 Additional Examples Solve the system by graphing. Graph the equations and find the intersection. The solution appears to be (–4, 2). x + 3y = 2 3x + 3y = –6 Check: Show that (–4, 2) makes both equations true. x + 3y = x + 3y = –6 (–4) + 3(2) (–4) + 3(2) –6 (–4) – –6 2 = 2 –6 = –6
