Answer 1

Question 1

$\left(\frac{-5+2}{2}, \frac{5-5}{2} \right)=\boxed{\left(-\frac{3}{2}, 0 \right)}$

Question 2

Let the coordinates of the other endpoint be (x,y).

$\left(\frac{x + 4}{2}, \frac{y+8}{2} \right)=( - 6,4) \\ \\ \implies \frac{x + 4}{2}=6 \implies x= - 16\\ \\ \frac{y+8}{2}=4 \implies y=0$

So, the coordinates of the other endpoint are (-16,0).
