Question

multiple - choice question
what kind of slopes do perpendicular lines have?
□ two perpendicular lines have the opposite reciprocal slope.
□ two perpendicular lines have the same slope.
□ two perpendicular lines have reciprocal slope.
rewatch

Explanation:

The slope of a line perpendicular to a given line with slope \(m\) is \(-\frac{1}{m}\), which means they have opposite - reciprocal slopes. Lines with the same slope are parallel, and just reciprocal slopes are not the characteristic of perpendicular lines.

Answer:

Two perpendicular lines have the opposite reciprocal slope.
