The captain of a boat with a bow (front) located at point B (1.5, 2.5) on the coordinate plane and a stern (rear) located at point S (4.5, 5.5) on the coordinate plane is approaching an island (0, 0) from the north-east side. However, the captain must re-position the boat so that the bow (point B) is approaching the island from the south-west. If the new position of the boat can be replicated by a reflection over the x-axis and then another reflection over the y-axis, what are the new coordinates of the bow (point B)?
