#### Explanation:

A line perpendicular to another line has an OPPOSITE RECIPROCAL slope.

For example, if a line had a slope of

Similarly, a line with slope

To find the slope of the perpendicular line, first find the slope of the original line.

The perpendicular line's slope will be the opposite reciprocal of
