Are two lines with different slopes are parallel?

No, only lines that have the same slope can be parallel.


How are the slopes of parallel lines related?

The slopes of two parallel lines will be the same.


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 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


What are two lines that have different slopes?

They are not parallel.


What is the relationship between the slopes of two parallel lines?

Parallel lines have the same slope.


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 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.


What do the slopes of two parallel lines have?

The same slope


Two Different lines are parallel if their slopes are?

equal


If two lines are parallel what do you know about their slopes?

If two lines are parallel, they have the same slope.(And if they are perpendicular, the product of their slopes is minus one - unless one line is horizontal and the other vertical.)


How do you find the slope of a parallel equation?

Two parallel lines have equal slopes.
