okay, you would need to plug in each answer choice to see which one makes the equation false.

(x,y) 
(-1,-7)
(-3,-10.5)
(0,-6)
(2,-3)

so now you know which ones are x and which ones are y, choose one of the points and plug into the equation. if it comes out false, then that point you chose is your answer.

3(-1)-2(-7)≥ 12
distribute
-3+14≥ 12
11≥ 12
which is false so A. (-1,-7)
Cannot be a solution
