Well, you can try them out and see if they produce a true statement.  For example, let's try answer C:

$$2(0)-11 = 11$$$$-11=11$$That's not true, so (0,11) is not a solution to that equation.

How about (8,5)? 
$$2(8)-5=11$$$$16-5=11$$$$11=11$$That is true, so (8,5) would be a solution (though it does not appear on your answer list).

2x -y = 11
-y = -2x + 11
y = 2x -11
im thinking
d but not sure
