Negative Reciprocals and Slopes of Perpendicular Lines

This tutorial discusses what negative reciprocals are and how that relates to slopes of perpendicular line segments.

nice explanation. understood clearly about neagative reciprocals. thank you

In this video it's shown that a negative slope (my example -4/7) becomes 7/4 which as it's shown is it's negative reciprocal negative reciprocal of a negative slope it's not a positive number even though the rule states that two negative signs make a positive sign the negative reciprocal of a negative slope it's just flipping the negative sign from the numerator to the denominator the same way you flip the numbers the reciprocal of a negative slope was a positive slope the line will never intersect thus this is
