The correct answer is B.
With negative numbers, the "smaller" the number looks the bigger it is.
-2 is greater than -4.
Positive numbers are greater than negative numbers so we have:
8 > -2 > -4

Answer:
x=8 and y=21
Step-by-step explanation:
12x-28=7x+12 (the 2 angles are equivalent)
12x-7x=12+28
5x=40
x=8
9y-77 + 12x-28 =180 (the sum of those 2 angles is a flat angle (180°))
9y-77+12*8-28=180
9y=180+28+77-96
9y=189
y=21
