Plug in the x-value for x in the equation and do the same for y.
Let's try answer choice D (because I already know it's correct).

We should substitute each and check in this case:
The maximum value can only be -3
is 4 - 2(2) ≤ -3 ?
Lets check:
4 - 4 ≤ -3
0 ≤ -3 ⇔ this is wrong
The solution is the last one because:
-1 - 2(1) ≤ -3
-3 ≤ -3
(1,-1)
