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.
Two Different lines are parallel if their slopes are?
equal
Is the slopes of two parallel lines are always equal?
Yes
Can two lines both have negative slopes and still be perpendicular?
Yes, as long as the negative slopes are both equal.
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
What kinds of slopes do parallel lines have?
The slopes of parallel lines are by definition equal.
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

Two Different lines are parallel if their slopes are?
equal
What 2 different lines are parallel if their slopes are blank?
equal
Is the slopes of two parallel lines are always equal?
Yes
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.
When is the product of the slopes of two perpendicular lines not equal to -1?
When the perpendicular lines are horizontal and vertical.
Can two lines both have negative slopes and still be perpendicular?
Yes, as long as the negative slopes are both equal.
How do you find a slope of a equation?
Two parallel lines have equal slopes.
What are the slopes of perpendicular lines called?
Slopes of line perpendicular to the x-axis are undefined.
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.
