The transformed equation of 14 x to the power of 2 end exponent minus 4 x y plus 11 y to the power of 2 end exponent minus 36 x plus 48 y plus 41 equals 0 when the axes are translated to (1, –2) is

shifting of origin is done when the aes are shifted parallely to a different location on the cartesian plane.
this results in change  of coordinates as: x=x'+h and y=y'+k
where h,k are the new origin.
