Solving systems of equations

Objectives: Students will be able to solve for a system of two equations using graphs. Students will be able to solve for a system of two equations using substitution and be able to check their work using graphs. Be able to create two intersecting lines from an intersection point Task: Solve the systems of equations first using substitution, then 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 Create two lines that intersect at the point: (-3, 6) (7, 13) (16, 2)
