In a coordinate plane two nonvertical lines are WHAT if and only if the product of their slopes is negative one?
Perpendicular
How can you use slope to decide whether two nonvertical lines are parallel?
They're parallel if their slopes are equal.
If the product of the slopes is what then the lines are what?
If the product is -1 then the lines are perpendicular to one another.
How do you calculate parallel and perpendicular lines in a given plane?
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.
If the product of the slopes of two lines equals -1 then the lines?
Are perpendicular to one another.
In a coordinate plane two nonvertical lines are WHAT if and only if the product of their slopes is negative one?
Perpendicular
If two nonvertical lines intersect what are the slopes?
With the information provided, all that can be said is that the slopes are two different real numbers.
In a coordinate plane the two nonvertical lines are parallel if and only if they have what slope?
-1 :)
How can you use slope to decide whether two nonvertical lines are parallel?
They're parallel if their slopes are equal.
Rectangle abcd lies in the xy-coordinate plane so that its sides are not parallel to the axes what is the product of the slopes of all four sides of rectangle abcd?
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
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
If the product of the slopes is what then the lines are what?
If the product is -1 then the lines are perpendicular to one another.
How do you calculate parallel and perpendicular lines in a given plane?
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.
The product of the slopes of perpendicular lines is always?
-1
What is the product of the slopes of perpendicular lines?
It is always -1.
What must be true about the slopes of two perpendicular lines neither of which is vertical?
In that case, the product of the slopes is equal to minus 1.
If the product of the slopes of two lines equals negative 1 then the lines?
Are perpendicular.
