What has to be true about the slopes of two perpendicluar lines that's neither vertical?
The slopes are negative reciprocals.
How do you know if two non-vertical lines are perpendicular?
They are perpendicular if their slopes are mutual negative reciprocals.
What are the slopes of perpendicular lines?
Negative reciprocals of one another.
Two numbers are if their product is -1?
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.
If two lines are perpendicular?
one slope is the negative reciprocal of the other

If two lines are 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.If the lines are perpendicular, their slopes are negative reciprocals.
What can you say about the slopes of two non-vertical perpendicular lines?
They are negative reciprocals Ex -1/2 and 2
What is the definition of a slope of parallel lines?
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
How do you know if two non-vertical lines are perpendicular?
They are perpendicular if their slopes are mutual negative reciprocals.
Lines that are perpindicular have slopes that are?
negative reciprocals of each other
What are the slopes of perpendicular lines?
Negative reciprocals of one another.
If two lines have slopes that are negative reciprocals of each other then they are if they have slopes that are the same then they are?
negative reciprocal slopes ---> the lines are perpendicular equal slopes ---> the lines are parallel
How do you know if two line segments are perpendicular?
their slopes are negative reciprocals.
Two numbers are if their product is -1?
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.
If two lines are perpendicular?
one slope is the negative reciprocal of the other
If the lines have slopes that are negative reciprocals?
If you have two lines that have negative recipricals (1 and -1 for example), the lines are perpendicular.
