Part A: y = x - 2 and y = x + 2

Part B: (11, 9); (12, 10); (13, 11); (14, 12); (15, 13); (16, 14) and (1, 3); (2, 4); (3, 5); (4, 6); (5, 7); (6, 8); (7, 9)

Part C: In the first table, Rachel's age is 2 years younger than Sean's. In the second table, Sean's age is 2 years older than Rachel's. Both relationships are functions because each input has exactly one output.

Part D: No; for example, when Sean is 14, Rachel is 12. 14 is not 12 times 2, so this rule cannot work.
