Solving Systems by Graphing

Solve each system by graphing. Then tell whether the system has one solution, infinitely many solutions, or no solution.

1. y = 3x + 5x + y = 3

2. y = 2x + 1y = 4x + 7

3. 3y = 3x – 6 y = x – 2

4. y = 2x + 1y = (-2/3)x + 5

5. y = 3x + 23x + y = 1

6. y = 5x 6x + y = -6

7. y = (1/2)x 6y = (1/4)x

8. y = 6x + 42 + y = 6x

9. 18x 3y = 21y = 6x + 7
