Hi ,
It is given that point ( k , k ) lies on the line
3x + 4y + 7 = 0 ,
substitute ( k , k ) in given equation, we get
3k + 4k + 7 = 0
7k + 7 = 0
7k = -7
k = ( -7 )/7
k = -1
I hope this helps you.

hey a small change
what if the equation was 3x+ky+7
3k + k × k + 7 = 0
k² + 3k + 7 = 0
we get imaginary roots .
