(-7 + X)/2 = 0
X = 7
(1 + Y )/2 = -8
Y = -17
endpoint is (7,-17)

Neal D. Uses the formula to solve. I use a little different method. How far away is -7 from 0? 7 right... So the other endpoint must be 7 away from 0.... So 0+7=7.... For the y coordinate 1 and -8 are 9 units away.... Since -8 is the midpoint -8 - 9 = -17.... So your coordinates of your other endpoint would be (7,-17) . A little hard to explain through typing.10/11/18
