Answer:
The coordinates of point S are (8,-2)
Step-by-step explanation:
we know that
The formula to calculate the midpoint between two points is equal to
[tex]M=(\frac{x1+x2}{2},\frac{y1+y2}{2})[/tex]
Let
Point S(x2,y2)
substitute the given values
[tex](1,2)=(\frac{-6+x2}{2},\frac{6+y2}{2})[/tex]
Solve for x2
[tex]1=(-6+x2)/2\\2=-6+x2\\x2=2+6=8[/tex]
Solve for y2
[tex]2=(6+y2)/2\\4=6+y2\\y2=4-6=-2[/tex]
therefore
The coordinates of point S are (8,-2)
