In this quetion we have to find the coordinate of point C on rotation by 180 degree about origin .
The rule for rotation by 180 degree about the origin is
![(x,y)-> (-x,-y)](https://tex.z-dn.net/?f=%28x%2Cy%29-%3E%20%28-x%2C-y%29)
It means , the x and y coordinates become opposite. That is
The new coordinate of point C (-3,4) is
![(- (-3),-4) = (3,-4)](https://tex.z-dn.net/?f=%28-%20%28-3%29%2C-4%29%20%3D%20%283%2C-4%29)
And that's the required answer.
