Answer
$V=-5i- j.$
Work Step by Step
We draw the given vector by sketching an arrow from the origin ti the point $(-5,-1)$, as shown in the figure.
Since $I$ is vector of length $|$ in the positive a-direction, $-5i$ will be a vector of length $-5$ in that same direction. Similarly $-1j$ will be a vector of length $-1$ in the positive $y$-direction. Hence, $V$ is the resultant of vectors $-5i$ and $-j$.
Therefore, we can write $V$ in terms of the unit vectors $i$ and $j$ as $V=-5i- j.$
