Perpendicular
They're parallel if their slopes are equal.
If the product is -1 then the lines are perpendicular to one another.
Take any two lines and look at their slopes. -- If the slopes are equal, then the lines are parallel. -- If the product of the slopes is -1, then the lines are perpendicular.
Are perpendicular to one another.
Perpendicular
-1 :)
With the information provided, all that can be said is that the slopes are two different real numbers.
They're parallel if their slopes are equal.
To find:The product of the slopes of all 4 sides of rectangle ABCDSolution:Topic(s): Coordinate geometryThe product of the slopes of perpendicular lines = -1.From the sketch above,Answer: (D) 1
If the product is -1 then the lines are perpendicular to one another.
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
Take any two lines and look at their slopes. -- If the slopes are equal, then the lines are parallel. -- If the product of the slopes is -1, then the lines are perpendicular.
It is always -1.
-1
In that case, the product of the slopes is equal to minus 1.
Are perpendicular.
