The following coordinate system represents a map, and each square of the grid is 1 square mile. point h has coordinates (2,−12) and represents the apartment, where hypatia and elibri live, point e has coordinates (16,7) and represents elibri's school, and finally point r has coordinates (−22,−15) and represents the location of the local restaurant, where hypatia works.
one day, elibri woke up and drove to her school. after her class, she went to hypatia's restaurant and had dinner there. finally, they came back together to their apartment.
