Notice that <em>v</em> points into the third quadrant since both of its components are negative. If you want a vector to point in the same direction, it would need to have the same sign on its components. So C is the correct choice.
The factor of 1/√80 comes from normalizing the vector <em>v</em>. Its norm/magnitude is
|<em>v</em>| = √((-4)² + (-8)²) = √(16 + 64) = √80
so the unit vector that points in the same direction as <em>v</em> is simply <em>v</em> / |<em>v</em>|.
The value of X in this equation would be -1.
