Linear Algebra:

For all the unit vectors u=[x,y,z]^T in R^3. Find the one for which the sum x+8y+2z is minimal. (u is a 3 x 1 vector)

2. Relevant equations

3. The attempt at a solution

I tried working this with the least squares method...it wasn't right. I am probably overthinking this.

Any help is appreciated! :)
