Answer:

(-3,-7)

Step-by-step explanation:

  • First we will get B by using this formula
  • [tex] \frac{x1 + x2}{2} [/tex]
  • [tex] \frac{ - 9 + - 1}{2} = - 5 [/tex]
  • [tex] \frac{y1 + y2}{2} [/tex]
  • [tex] \frac{ - 4 + - 1}{2} = 1[/tex]
  • E is mid point between B and D
  • To get d we will use the same formula
  • [tex] \frac{ - 5 + x}{2} = - 4 \\ x = - 3[/tex]
  • [tex] \frac{1 + y}{2} = - 3 \\ y = - 7[/tex]
  • So D = (-3,-7)
