A pizza chain guarantees delivery in 30 minutes or less. All orders are processed through a central office whose job, when an order is received, is to find the closest store in order to minimize the distance for its drivers. The company has set up a grid system, similar to the Cartesian plane, to locate its stores. The lines on the grid represent the major streets that run north-south and east-west.
In the portion of the company's grid map shown, the pizza chain has stores at locations A(-8,5), B(9,-3) and C(9,5 . If a pizza is to be delivered to a location in the grid at the origin, which store should the central office call?
