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)
