Answer:
d) ordered pairs are equal
e) ordered pairs are not equal
Step-by-step explanation:
d) ( 3+4 , 2 - 1)  
 x-co ordinate = 3 + 4= 7
y-co ordinate = 2 - 1  = 3
(3+ 4 , 2-1) = (7 , 3)
(3+4 , 2-1)  & ( 7 ,3) are equal
f)Compare the x -co ordiante and y - co ordiante of the two pairs
            p +q = q + p        {addition closed under commutative property}
       but q - p ≠ p - q        {Subtract is not closed under commutative}
 (p +q, q - p) & ( q + p , p -q ) are  not equal
