Can somebody help me with this math problem?

Answer:
i can't give answer because i cant see full graph but plot point A then draw a diagonal line through point M until your in the top right square and the line hits a point
Step-by-step explanation:
Answer: (-11, -5.5)
Step-by-step explanation:
Use Midpoint formula: [tex](\frac{x1+x2}{2} ,\frac{y1+y2}{2} )[/tex]
Midpoint M= (-9, -3)
(x1, y1)=(-7, -0.5)
-------------------------------------------------
[tex]\frac{x1+x2}{2}[/tex]=-9
-7+x2=-18
x2=-11
---------------------------------------------
[tex]\frac{y1+y2}{2}[/tex]=-3
-0.5+y2=-6
y2=-5.5
(-11, -5.5)
Hope this helps!! :)
