Thats gonna be region A.
lets check...this point is in that region (-1,3)
now we sub into our equations and see if it is true
y < = -5/2x + 4 y > = -1/2x - 2
3 < = -5/2(-1) + 4 3 > = -1/2(-1) - 2
3 < = 5/2 + 4 3 > = 1/2 - 2
3 < = 5/2 + 8/2 3 > = 1/2 - 4/2
3 < = 13/2 3 > = - 3/2
3 < = 6 1/2...true 3 > = - 1 1/2...true
so it is region A...100% sure
