Question 1204092
If M is the midpoint of XY, find the coordinates of X if 
The mid point formula is given by {{{ ((x1+x2)/2 , (y1+y2)/2) }}}where x1y1 and x2y2 are the co ordinates of the end points of the segment and (x,y) are the cordinates of mid point.

M (-3,-1) and Y (-8,6)

Let coordinates of X  be(x2,y2)

-3 = (-8+x2)/2

2*-3= -8+x2

-6+8=x2
x2=2

-1= (6+y2)/2

-1*2= 6+y2

-2=6+y2

y2=-8
X~(2,-8)
