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 coordinates of D

Question

 i cant find the answer anywher

e

Answer 1

((-9 - 1)/2, (-4 + 6)/2) = (-5,1)

 

((-5 + x)/2, (1 + y)/2) = (-4,-3)

 

(-5 + x)/2 = -4

-5 + x = -8

x = -3

 

(1 + y)/2 = -3

1 + y = -6

y = -7

 

(-3,-7)
