Answer 11

process of elimination...

look at your first points...a = -1 and b = 3

now look at your answer choices..
(a) b = a + 4
now sub
3 = -1 + 4
3 = -3 (incorrect)
so you know it is not this answer choice.

now do the same for the other answer choices...sub in your points and if the answer comes out true, you got it.
You can then check your other points into that answer and they should all come out true
