- Parallel Lines (Yellow):
- Box 1: y = 3x - 7 and y = 3x + 1
- Box 4: 2x + 7y = 28 and 7x - 2y = 4
- Box 6: x + y = 7 and x - y = 9
- Box 10: 5x - 10y = 20 and y = -2x + 6
- Box 12: x = 4 and x = -6
- Perpendicular Lines (Light Blue):
- Box 2: y = -2/5x + 3 and y = 2/5x + 8
- Box 5: y = -5x + 1 and x - 5y = 30
- Box 7: y = -4x - 1 and 8x + 2y = 14
- Box 9: 4x + 9y = 18 and y = 4x + 9
- Box 11: 10x + 8y = 16 and 5y = 4x - 15
- Neither (Uncolored):
- Box 3: y = -1/4x and y = 4x - 5
- Box 8: y = 1/3x + 9 and x - 3y = 3
- Box 13: -9x + 12y = 24 and y = 3/4x - 5
- Box 14: y = x - 3 and x - y = 8
- Box 15: y = 5/3x + 7 and 6x - 10y = 10
- Box 16: x - 2y = 18 and 2x + y = 6
- Box 17: x = 1 and y = -8
