Question:
The image of the point $(3,5)$ in the line $x-y+1=0$, lies on :
Correct Option: 1
Solution:
Image of $\mathrm{P}(3,5)$ on the line $\mathrm{x}-\mathrm{y}+1=0$ is $\frac{x-3}{1}=\frac{y-5}{-1}=\frac{-2(3-5+1)}{2}=1$
$x=4, y=4$
$\therefore$ Image is $(4,4)$ Which lies on $(x-2)^{2}+(y-4)^{2}=4$
