How do you use the slopes and y-intercepts to determine if two lines coincide or are parallel?

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.

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
Which lines or segments are parallel justify your answer with a theorem or postulate?
Parallel lines are parallel. Proof they have same slopes
Determine whether the graphs of the equations are parallelperpendicular or neither?
Base on the slope of two linear equations (form: y = mx+b, where slope is m): - If slopes are equal, the 2 graphs are parallel - If the product of two slopes equals to -1, the 2 graphs are perpendicular. If none of the above, then the 2 graphs are neither parallel nor 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
How do you determine if they are parallel perpendicular or neither?
That depends on the specific situation. You may want to measure angles (perpendicular lines are at a right angle, i.e., 90°). If you have equations for line, write them in the slope-intercept form. Parallel lines have the same slope. If lines are perpendicular, the product of their slopes is -1.
How can you use the slopes and y-intercepts to determine if two lines are parallel?
If the lines are straight and have the same slope they are parallel, no matter what the y intercept is
How are the slopes of parallel lines related?
The slopes of two parallel lines will be the same.
What kinds of slopes do parallel lines have?
The slopes of parallel lines are by definition equal.
Have slopes that are the same?
same slopes = parallel lines
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.
How do you find the perimeter of a rectangle with only the slopes given?
You cannot. Given only the slopes, it is impossible to determine the distance between the parallel lines and so the lengths of the sides. Without that you cannot calculate the perimeter.
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 is the word for equal slopes?
parallel
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 relationship of the slopes of parallel lines?
They are the same.
What are two lines that have different slopes?
They are not parallel.
Can 2 parallel lines have different slopes?
No
