What is the product of the slopes of perpendicular lines?
It is always -1.
If the product of the slopes of two lines equals negative 1 then the lines?
Are perpendicular.
What must be true about the slopes of 2 perpendicular lines?
The slopes of two perpendicular lines are negative inverses of each other. In other words, the two slopes when multiplied together equal -1.
What pair of slopes could represent perpendicular lines?
Negative reciprocal slopes always represent perpendicular lines.
How do you determine if 2 lines are parallel perpendicular or neither?
Two lines are parallel if and only if they have the same slope. Two lines are perpendicular if the product of their slopes is -1. If neither of these conditions are met, the lines are nether parallel, or perpendicular.
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.
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 two lines are perpendicular what is the product of their respective slopes equal to?
The sum of their slopes is 0. The product of two lines that are perpendicular with slopes m and -m i= -m^2 Hmmmm... Seems we're both wrong again. The answer is -1. See the link I attached.
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.
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.
How do slopes of perpendicular lines compare?
Slopes of perpendicular lines will be opposite reciprocals. This means that the slopes have opposite signs and that one is 1/ the other. For example, 2 and -1/2.
What is the slope of perpidicular lines?
When two lines are perpendicular to each other the product of their slopes is equal to -1.m1*m2 = -1
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
If the product of the slopes of two lines equals negative 1 then the lines?
Are perpendicular.
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.
Do two lines that have slopes of 1 and -1 are perpendicular?
