Emma lives at the point (-5, -17). She wants to go to the closest mall. There are two malls on the map. Mall AA is at (-4, -9), and Mall BB is at (-5, -4). On the map she can only travel vertically or horizontally, one unit at a time. She cannot go diagonally. So she could go from (1,3) to (1,4) or (1,3) to (2,3), but not from (1,3) to (2,4). Which mall is closer to her?
