Quick comprehension check

Point A is located at (2, 3) on a coordinate plane, and point B is located at (6, 7). Use the midpoint formula to find the coordinates of the midpoint M of line segment AB. A straight hiking trail connects two campsites. Camp 1 is at coordinates (-4, 1) and Camp 2 is at coordinates (8, -5). Use the midpoint formula to determine the location of the trail's halfway point. A city planner is designing a new park. They want to place a water fountain exactly halfway between the park's entrance, located at (0, 0), and the main picnic area, located at (10, 12). Use the midpoint formula to find the coordinates where the fountain should be placed.
