1. Which of the following ordered pairs belongs to the binary
relation p on N?
a) x p y if & only if x + y < 7; (1,3), (2,5), (3,3), (4,4)
c) x p y if & only if 2x + 3y = 10; (5,0), (2,2), (3,1), (1,3)
2. S = {0, 1, 2, 4, 6}. Which of the following relations are
reflexive, symmetric, anti symmetric, and transitive? Find the
closures for each category for all of them
1.p = { (0,0), (1,1) (2,2) (4,4) (6,6) (0,1) (1,2) (2,4) (4,6)}
2. p = {(0,0), (1,1) (2,2) (4,4) (6,6) (4,6) (6,4)}
3. p = {(0,1), (1,0) (2,4) (4,2) (4,6) (6,4)}
stuck on both of these (btw it's that p isn't the letter p it's a logic symbol

c) x p y if & only if 2x + 3y = 10; (5,0), (2,2), (3,1), (1,3) since each point is related to one another because they belong to the given function.
Good luck!
