A) $\mathbf { u } = - 6 \mathbf { i } + 6 \mathbf { j }$
B) $\mathbf { u } = - 6 \mathbf { i } + 7 \mathbf { j }$
C) $\mathbf { u } = - 3 \mathbf { i } - 2 \mathbf { j }$
D) $\mathbf { u } = - 6 \mathbf { i } + \mathbf { j }$
E) $\mathbf { u } = - 6 \mathbf { i } - 2 \mathbf { j }$

Quizplus · Accepted Answer

The vector u can be found by subtracting the coordinates of the initial point P from the coordinates of the terminal point Q as ($1-7$, $4-3$) = ($-6$, $1$). Therefore, the vector u can be expressed as $-6 \mathbf{i} + \mathbf{j}$.
