From the diagram, the line of reflection is


y=x

Hence, the rule of reflection is


R(x,y)=(y,x)

Therefore, the reflection rule R(x,y) = (y,x), and the equation of the line t is y = x

Check


\begin{gathered} P(2,3)\to P^(\prime)(3,2) \\ Q(-2,4)\to Q^(\prime)(4,-2) \\ R(-2,0)\to R^(\prime)(0,-2) \end{gathered}
