Please learn the difference between geography and geometry.

If you post your GEOMETEY answers and someone will probably check them for you.

A. 1.5
B. -1.5
C. 2
D. -3
==================================
I see no attempt by you to do these.
I will show how to do two. Then you try.
first:
halfway between -9 and +6
is
(-9 + 6 )/2 = -3/2 = -1.5
so B.
========================================
second
2. Find the coordinates of the midpoint ~hx(line over hx) given that H(-1,3) and X(7,-1).
A. (3,1)
B. (0,4)
C. (-3,1)
D. (-4,0)
=============================
halfway between in x = (-1+7)/2 = 6/2 = 3
halfway between in y = (3-1)/2 = 2/2 = 1
so
(3,1)
which is A.
==================
Your turn.
1. -1.5
2. (3,1)
3. 12.2
4. 165
