Erin writes the set of ordered pairs below. The set represents a function. {(3,−3),(5,0),(−1,4),(−6,7)}

Erin claims that she can add any point to the set and have the set still represent a function.

Which of the following points can be used to show that Erin's claim is incorrect? Select THREE that apply.
A.
(−6,1)

B.
(−1,9)

C.
(0,5)

D.
(1,7)

E.

PLEASE SELECT THREE AND NOT JUST ONE.
Also, I tried plotting these points and they don't form a line so please take that into consideration.
