Q:
# b is the midpoint of AC and E is the midpoint of BD if A-9,-4 C-1,6 and E-4,-3 find the coirdinates of D

Accepted Solution

A:

Answer:\(B=(\frac{}-9-1{}{}2{},\frac{}-4+6{}{}2{} ) (midpoint formula)\\B=(-5,1)\\\\Then using midpoint formula again,\\E=(-4,3)=(\frac{}-5+x{}{}2{} =-4,\frac{}1+y{}{}2{} =3)\\so \\x=-3\\y=5\\\\D=(-3,5)\):
