Graphing Systems of Equations
Lesson 3-1 Multiple Choice: Which ordered pair of numbers is the is the solution to the system? A. (1,-4) B. (-6,-4) C. (-1,-3) D. (-3,-2) x + 2y = -7 2x - 3y = 0

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

Graphing Systems of Equations
Lesson 3-1 Additional Examples Solve the system by graphing. Check your solution. 2x + y = 5 -x + y = 2
