Equation of first line : $\sqrt{2}$ x – y + 4 $\sqrt{2}$ k = 0 ….(1) and equation of second line : $\sqrt{2}$ k x – k y + 4 $\sqrt{2}$ k = 0 i.e.

$\sqrt{2}$ x + y – 4 $\sqrt{2}$ = 0 ….(2).

First equation represents parallel lines with constant slope ( $\sqrt{2}$ ) but varying intercept as k is parameter.

When these lines will intersect the second given line, the locus of point of intersection is nothing but the second line.

Hence required equation of locus is $\sqrt{2}$ x + y – 4 $\sqrt{2}$ = 0.
