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
Adapted from an activity by GeoGebraTube user ericah.
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)
