6-126.

Construct a unit vector that is perpendicular to $5\mathbf{i} + 12\mathbf{j}$. Note that there are two solutions.

If the slope of a line or segment if $12/5$, then the slope of the perpendicular segment is $−5/12$.

To construct a unit vector, divide each component of the original vector by its length.
