How can you determine if two lines will intersect using the slope?
To determine if two lines will intersect using their slopes, compare the slopes of the two lines. If the slopes are different, the lines will intersect at one point. If the slopes are the same and the y-intercepts are different, the lines are parallel and will not intersect. If both the slopes and y-intercepts are the same, the lines are coincident and overlap entirely.
Two Different lines are parallel if their slopes are?
equal
How do you know if two lines are intersecting lines with out graphing?
For two dimensional lines: Get the formulas for the two lines into a format so that you can evaluate the slope. If the slopes are different, then they will intersect. If the slopes are the same, then you have two parallel lines, or possibly, the two equations describe the same line.
Will two lines with different y intercept cross each other?
They will, if they have different slopes.
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
If two lines have different slopes and different y intercepts how many points of intersection are there?
If two lines have different slopes, then they intersect at exactly one point. It makes no difference what their y-intercepts are.
Two lines are parallel if and only if their slopes are?
When their slopes are of the same value and their y intercepts are different
Are two lines with different slopes are parallel?
No, only lines that have the same slope can be parallel.
If two nonvertical lines intersect what are the slopes?
With the information provided, all that can be said is that the slopes are two different real numbers.
How do you know if two lines are intersecting lines with out graphing?

Two lines that have different slopes but the same y-intercept?
no solution
Will two lines with different y intercept cross each other?
They will, if they have different slopes.
How many solutions are there when two lines have different slopes and y-intercepts?
If they are straight lines, then one solution.
How are the slopes of parallel lines related?
The slopes of two parallel lines will be the same.
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 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.
