Objectives: [br]Students will be able to solve for a system of two equations using graphs.[br]Students will be able to solve for a system of two equations using substitution and be able to check their work using graphs.[br]Be able to create two intersecting lines from an intersection point[br][br]Task:[br]Solve the systems of equations first using substitution, then graphically using the geogebra applet. [br]1. 2x + y = 9[br]3x – y = 16[br]2. x – 2y = –9[br]x + 3y = 16[br]3. 2x – y = 9[br]3x + 4y = –14[br]Create two lines that intersect at the point:[br](-3, 6)[br](7, 13)[br](16, 2)
