HI!!

misty1212 · Answer

pick the ones with no repeat in the first coordinate

anonymous · Answer

set A is 1-1 meaning for every (x,y) x corresponds to one y

misty1212 · Answer

A has no repeats for sure 
all the first numbers are different
how about B?

misty1212 · Answer

not to be argumentative, but a set cannot be 1 to 1, only a function can

@xo_kansasprincess_xo  you got this?

anonymous · Answer

Not really..lol
