Thread: vector question help pls

the line L has equation
r=4i +2j -k + t(2i -j -2k). given that l lies in the plane with equation
2x + by+ cz =1 where b and c are constants

find the values of b and c

and also

the point P has psition vector 2j + 4k. show that the perpendicular distance frm P to L is square root of 5

The point must be in the plane .
This dot prpduct must hold.
That give two equations in two variables.
