all you have to do it plug in the coordinations into the equation to find which is true. now let’s check it.
x - y = -4. (-5, -1)
-5 - (-1) = -4
-4 = -4 so this is correct.
x - y = -4. (3, 7)
3 - 7 = -4
-4 = -4. so this is correct
x - y = -4 (-3, 3)
-3 - 3 = -4
-6 = -4. so this is incorrect.
x - y = -4 (0, 3)
0 - 3 = -4
-3 = -4 so this is incorrect
x - y = -4 (-2, 6)
-2 - 6 = -4
-8 = -4. so this is incorrect
so your answers would be a & b.
hoped this helped! xx
