Question

I don’t get 9.) so if anyone can’t skip it I need help with 10.) too

Answer 1

I will help with 10 i don't get 9 sorry so the answer is (a) F(5,4)

Explanation:

So you have the midpoint and you put f(x, y) and D(-3,-8)

So

E=(x-3/2, y-8/2) =(1,-2) so

X-3/2 =1 , x-3=2 so x = 5

And y-8/2 = - 2. , so y-8 = - 4. , so y =4

So F =(5, 4)

Answer 2
