Activity 1. What Satisfies both?
Directions: Solve each of the following systems of linear equations graphically then check.
You may also use GeoGebra to verify your answer.
1. x + y= - 7
3. 3x + y = 2
5. y = 5x - 2
y = x + 1
+
2y = 4 – 6x
5x - 3y = -14
2. x - y = 5
4. x + y = 4
6. 2x – 3y =5
X + 5y = -7
2x - 3y = 3
3y = 10 + 2x
