If the lines are in the form y = mx + c, the m values multiplied together should equal -1.
Otherwise, the dot product of the two slope vectors should equal 0.

Do Perpendicular lines have opposite reciprocal slopes?
Actually it IS. perpendicular lines have opposite reciprocal slopes and parallel lines have the same slope.
What are the slopes of perpendicular lines called?
Slopes of line perpendicular to the x-axis are undefined.
Do two lines that have slopes of 1 and -1 are perpendicular?
2
What is the relationship between the slopes of two parallel lines?
Parallel lines have the same slope.
The product of the slopes of perpendicular lines is always?
-1
How do parallel and perpendicular slopes compare or their y intercept?
There is no relationship between the slopes of parallel or perpendicular lines and their y-intercepts.
What represents the correct relationship between the slopes of perpendicular lines?
If the slopes are m1 and m2 then m1*m2 = -1 or m2 = -1/m1.
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.
Explain what is the relationship between the equations of perpendicular lines?
The relationship between perpendicular lines lies in there slopes. The slope of one line is the opposite reciprocal of the other. Written mathematically, the lines y=m*x +b and y =(-1/m)*x +c are perpendicular lines (note the y-intercepts do not need to be equal or even related to each other).
Would perpendicular lines have negative or positive slopes?
I believe they have Negative Slopes as stated by my Geometry Book. "Perpendicular Lines Have Slopes Which Are Negative ___"
What pair of slopes could represent perpendicular lines?
Negative reciprocal slopes always represent perpendicular lines.
Do Perpendicular lines have opposite reciprocal slopes?
Actually it IS. perpendicular lines have opposite reciprocal slopes and parallel lines have the same slope.
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 are the slopes of perpendicular lines called?
Slopes of line perpendicular to the x-axis are undefined.
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
When is the product of the slopes of two perpendicular lines not equal to -1?
When the perpendicular lines are horizontal and vertical.
How do you use slope to determine if two lines are perpendicular?
You have to know the slopes of both lines. -- Take the two slopes. -- The lines are perpendicular if (one slope) = -1/(the other slope), or the product of the slopes equals to -1.
