In Exercises 1-3, draw graphs corresponding to the given linear systems. Determine geometrically whether each system has a unique solution, infinitely many solutions, or no solution. Then solve each system algebraically to confirm your answer.
1. x + y = 0
2x + y = 3
2. x - 2y = 7
3x + y = 7
3. 3x - 6y = 3
