The unit vector directed from point A(2,5,1) to point B(-1,4,-2) can be expressed as

$0 . 69 \overline{a_{x}} + 0 . 23 \overline{a_{y}} + 0 . 69 \overline{a_{z}}$

$0 . 69 \overline{a_{x}} - 0 . 23 \overline{a_{y}} + 0 . 69 \overline{a_{z}}$

$0 . 69 \overline{a_{x}} - 0 . 23 \overline{a_{y}} - 0 . 69 \overline{a_{z}}$

$0 . 69 \overline{a_{x}} + 0 . 23 \overline{a_{y}} - 0 . 69 \overline{a_{z}}$
