Objectives: Students will be able to solve for a system of two equations using graphs. Be able to create two intersecting lines from an intersection point Adapted from an activity by GeoGebraTube user ericah. Task: Solve the systems of equations graphically using the geogebra applet. 1. 2x + y = 9 3x – y = 16 2. x – 2y = –9 x + 3y = 16 3. 2x – y = 9 3x + 4y = –14

Task: Solve the systems of equations graphically using the geogebra applet. 4. 2x + y = 8 -2x – y = 16 5. 3x – 6y = –9 x - y = -3 6. 2x – y = 9 x + 4y = –5 7. Create two lines that intersect at the point: (-3, 6)
