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.
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.
How are the slopes of the sides of a parallelogram related?
The slopes of the opposite sides are equal.
Two Different lines are parallel if their slopes are?
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
How do you know if two line segments are parallel?
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 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 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.
How do you find a slope of a equation?
Two parallel lines have equal slopes.
How do you find the slope of a parallel equation?
Two parallel lines have equal slopes.
What are the characreristics of two lines that coincide?
They have equal slopes, equal y-intercepts, equal x-intercepts,and if they are line segments, then they have equal lengths.
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 adjacent sides of a rectangle must have?
negative reciprocal slopes
