1.) Find vector parametric equation for the line through the point P=(1,4,–5) perpendicular to the plane –5x+3y–4z=–4.

Any help would be great

Tom, you've been here long enough to know the rules!
 
I know I just need a hint
like how to find the normal vector or something
i wasn't hoping for the answer
 
The normal vector to a plane given by an equation ax+by+cz=0 is easy: all vectors (x,y,z) in the plane satisfy that equation, so are clearly normal to the vector... Replacing the 0 by a constant just shifts the plane, so the normal vector doesn't change.
 
thx guys for the hint but I'm to late... just have to get it done earlier next time
