Homework Statement
Find the coordinates of the symmetric point of the point M(3,4,7) from the plane 2x-y+z+9=0
Homework Equations
The Attempt at a Solution
I found the equation of the plane which the symmetric point is staying at:
2x-y-z+27=0
Also I found the distance between M(3,4,7) and the symmetric point:
[tex]\sqrt{(x-3)^2+(y-4)^2+(z-7)^2}=2*3*\sqrt{6}[/tex]
I need one more condition to solve the system.
The coordinate from my textbook results which I need to find is: [tex]M_s(-9,10,1)[/tex]
