negative reciprocal slopes ---> the lines are perpendicular equal slopes ---> the lines are parallel
Horizontal lines have a slope of zero, and the slope of vertical lines is undefined. Parallel lines have equal slopes, and perpendicular lines have slopes that are negative reciprocals of each other. So we can say that: Two nonvertical lines are parallel if and only if they have the same slope. Two lines are perpendicular if and only if their slopes are negative reciprocals of each other. That is, if the slopes are m1 and m2, then: m1 = - 1/m2 or (m1)(m2) = -1
Two linear equations (or lines) with the same y-intercept and different slopes are intersecting lines. They intersect at the y-intercept. If the slopes are negative reciprocals (ex: one slope is 3 and one slope it -1/3) then they are perpendicular lines.
their slopes are negative reciprocals of each other. and they make a right angle when they intersect.
Well, if you use the point on the graph that the two lines intersect the slopes would be defined by the y intercepts. This doesn't really help or answer your question, I'm just thinking out loud.
negative reciprocal slopes ---> the lines are perpendicular equal slopes ---> the lines are parallel
If you have two lines that have negative recipricals (1 and -1 for example), the lines are perpendicular.
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
Horizontal lines have a slope of zero, and the slope of vertical lines is undefined. Parallel lines have equal slopes, and perpendicular lines have slopes that are negative reciprocals of each other. So we can say that: Two nonvertical lines are parallel if and only if they have the same slope. Two lines are perpendicular if and only if their slopes are negative reciprocals of each other. That is, if the slopes are m1 and m2, then: m1 = - 1/m2 or (m1)(m2) = -1
They are negative reciprocals Ex -1/2 and 2
perpendiculars("Opposite" is a pretty arbitrary condition in math. The slopes are negative reciprocals.)and by negative that person means the opposite of what it is already, negative or positive, it's not always negative
their slopes are negative reciprocals.
They are perpendicular if their slopes are mutual negative reciprocals.
