If you have two lines that have negative recipricals (1 and -1 for example), the lines are perpendicular.
Negative reciprocals of one another.
The slopes are negative reciprocals.
Two numbers are negative reciprocals if their product is -1. The numbers 1/2 and -2 are negative reciprocals. Their product is -1. This is often seen in problems involving the slopes of two lines. The slopes of perpendicular lines are negative reciprocals. Their product is -1.
one slope is the negative reciprocal of the other
They are perpendicular if their slopes are mutual negative reciprocals.
If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.
negative reciprocal slopes ---> the lines are perpendicular equal slopes ---> the lines are parallel
negative reciprocals of each other

one slope is the negative reciprocal of the other
of mutually perpendicular lines.
They are perpendicular if their slopes are mutual negative reciprocals.
It took me forever to find this answer, but the answer is "Reciprocals" Good Luck!
