If the lines are straight and have the same slope they are parallel, no matter what the y intercept is
same slopes = parallel lines
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.
They are not parallel.
No
they have the same slopes
If the slopes are different the lines are neither - they intersect. They are parallel or coincident if the slopes are the same. Then, if the y-intercepts are the same they are coincident while if the y-intercepts are different, they are parallel.
The slopes of parallel lines are by definition equal.
The slopes of two parallel lines will be the same.
same slopes = parallel lines
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 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.
negative reciprocal slopes ---> the lines are perpendicular equal slopes ---> the lines are parallel
No, only lines that have the same slope can be parallel.
Parallel lines have the same slope.
Parallel lines are parallel. Proof they have same slopes
Parallel lines
They are not parallel.
