Answer:
   (3, 2)
Step-by-step explanation:
Reflection across y=x swaps the coordinates:
   (x, y) ⇒ (y, x)
Dilation by a factor of 1/2 multiplies each coordinate by 1/2.
   (x, y) ⇒ (x/2, y/2)
The combination of these transformations gives you ...
   (x, y) ⇒ (y/2, x/2)
   (4, 6) ⇒ (3, 2)
 
        
             
        
        
        
I believe 25 has to be added as
(x*5)^2 = x^2 + 10x + 25
