If x+y=k is a normal to the parabola y^(2)=12x , then the value of k is-

If x + y = k is a normal to the parabola y^(2) = 12x then the value of k is

If the line x-3y+k=0 touches the parabola 3y^(2)=4x then the value of k is

If the line y=x+k is a normal to the parabola y^(2)=4x then find the value of k.

If 2 x+y+lambda=0 is a normal to the parabola y^(2)=8 x, then lambda=
