```										Hi,

if  v will join these two pts , line joining these points will be perpendicular to mirror ,

more over the mirror will be equidistnt frm both points , hence will be passing through the mid point of the line joining these.

mid pt = {(4+2)/2, (-6+1)/2} = (3, -5/2)

slope =  -1/m    where m = slope of line joing pts

=  -{4-2/-6-1}= 2/7

now eqn =>  y-1=2/7*(x-2)

7y -2x -3=0

```
