Answer:
1. (4,6)
2. (-4,-6)
3. (2.5,7)
4. (5,-3)
5. (1,7)
Explanation:
You can find the midpoint of a line segment given 2 endpoints, (x1, y1) and (x2, y2). Add each x-coordinate and divide by 2 to find x of the midpoint. Add each y-coordinate and divide by 2 to find y of the midpoint.
Calculate the midpoint, (xM, yM) using the midpoint formula:
(xM,yM)=(x1+x2,y1+y2)
 2 2
