Unit vectors
Hello

I need to find:

An unit vector parallel to the line $x=3t + 1, y=16t-2, z=-(t+2)$

An unit vector orthogonal to the plane $x-6y+z = 12$

An unit vector orthogonal to the planes $8x+y+z = 1$ and $x-y-z =$

Thanks

What have you tried? Where are you stuck? Have you reviewed your class notes and textbook?
