```										Dear anand s
let the reflection is (h,k)
mid point of (h,k) and (4,-13) lies on straight line
and slope of line and the line joining by point(h,k) and (4,-13) are perpendicular
slope of the line =-5
slope of line  joining by point(h,k) and (4,-13)=(k+13)/(h-4)
so (k+13)/(h-4) * (-5) =-1
5k +65 =h-4
or  h= 5k +69 ......1

and mid point lie on line
so 5(h+4)/2   + (k-13)/2   +6  = 0
or 5(h+4)   + (k-13)   +12  = 0
5h + k +19 =0..............2
solve above  two equation
point(-1 ,-14)
