Find the position vector for the vector having initial point P and terminal point Q.
-$$\mathrm { P } = ( - 1 , - 1,0 ) \text { and } \mathrm { Q } = ( - 3,3 , - 4 )$$
A) $v = 2 i - 4 j + 4 k$
B) $v = - 3 i + 4 j + 5 k$
C) $v = - 3 i + 4 j - 3 k$
D) $v = - 2 i + 4 j - 4 k$

Question

Quizplus · Accepted Answer

The position vector from P to Q is found by subtracting the coordinates of P from Q: $(-3 - (-1), 3 - (-1), -4 - 0) = (-2, 4, -4)$, which corresponds to $-2i + 4j - 4k$.
