You can put this solution on YOUR website! P(6,-2),M(0,5),Q(x2,y2)
Since formula for midpoint is:
and
Then formula for and is:

where is the coordinate of the , and the coordinate of the
so, we have:






so, Q(x2,y2)=Q(-6,12)
Checking:
and 
and 
and 
and
= ,
We got the right midpoint.
Thus, the coordinates of Q are ( , )
