Question 29518
To find the correct answer you need to substitute 
each of the (x,y) pairs into the given equation to
see which pair gives you a true statement.
Trying (1,2) you get 3(1)=2(2)-1 or 3=3.
(1,2) gives you a true statement. 
You then try (-1,-1); it also works.
So does (-2,-5.2)
Only (0,-1/2) does not give a true statement.
Maybe you were asked to find the pair that was NOT in the relation.
