Question

Whats the answer? A) B) C) D)

Answer 1

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
