Find the of the image of the point (-2,3) about the line x+2y-9=0.

The image of the point (2,3) in the line y = -x is

Find the image of the point (2,-1,3) in the plane 3x-2y+z-9=0

Find the image of the point P(1, 2) in the line x-3y+4=0

Find the image of the point : (2,-1,3) in the plane 3x-2y-z=9

Find the image of the point (1, 2) in the line x - 3y + 4 = 0 .

Assuming that straight lines work as the plane mirror for a point, find the image of the point (1,2) in the line x - 3y + 4 =0 .
