The coordinates of the vertices of a quadrilateral are P(2,3), Q(-3,3), R(9,-2), and S(1,1). Quadrilateral PQRS was translated 9 units to the left and 1 unit up to create P'Q'R'S'. Which rule describes this transformation?

• (X,Y) -> (X, Y + 3)

• (X,Y) -> (X + 9, Y - 1)

• (X,Y) -> (X + 9, Y + 1)

• (X,Y) -> (X - 9, Y + 1)
