Any line that is parallel to another line will have the same slope. So if line AB's slope is zero and line CD is parallel to AB, then its slope will also be zero. The slope of line CD, when perpendicular to AB, will be infinity. If line AB has a slope of zero that means its just a horizontal line passing some point on the y-axis. A line that is perpendicualr to this one will pass through some point on the x-axis and therefore have an infinite slope.

If two lines are perpendicular do the have the same slope?
No but if the two lines are parallel then they will have the same slope.
How can you prove that a constructed line is parallel to a given line Assume that the transversal line is not perpendicular to the other lines?
If the lines have the same slope but with different y intercepts then they are parallel
Is y -7 and y 5 parallel perpendicular or neither?
Neither because the value of the x slope has not been given nor have proper straight line equations been given
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.
What is the slope of a line that is perpendicular to the line whose equation is 2y x - 1?
Get the slope of the given line, by putting it into slope-intercept form. Then you can divide minus one by this slope, to get the slope of any perpendicular line.
Is an undefined slope and a slope of 0 parallel?
No, they are perpendicular.
What is the parallel slope of 2?
A parallel slope to 2 is 2. A perpendicular slope to 2 is (-1/2).
How can we tell if two lines are parallel perpendicular or neither just from their equations?
If the slope of the equations are the same then they are parallel If the slope of the equations are minus reciprocal then they are perpendicular If the slope of the equations are different then they are neither
Do perpendicular lines have the same exact slope?
No, parallel lines have exactly same slope Perpendicular line have a slope that is negative reciprocal of each other that is if m = slope of line then slope of perpendicular line is -1/m
For the line given by y2x find the slope of a line that is Parallel m Perpendicular m?
The line y = 2x If you put it into the form y = mx + b, you have y = 2x + 0 so the slope is 2. Lines parallel to that line have the same slope, 2. Perpendicular lines have slopes that multiply to -1. The slope of a perpendicular line to a line of slope 2 would be -1/2.
If two lines are perpendicular do the have the same slope?
No but if the two lines are parallel then they will have the same slope.
How can you prove that a constructed line is parallel to a given line Assume that the transversal line is not perpendicular to the other lines?
If the lines have the same slope but with different y intercepts then they are parallel
Do parallel lines have negative reciprocals?
The slope of parallel lines are the same, but the slope of perpendicular lines are negative reciprocals of each other.
Does perpendicular lines have the same slope?
No, lines have the same slope if and only if they are parallel to each other.
Given that the slope of a line is 1 3 what is the slope of a line that is perpendicular to it?
If we call the slope m we can say that the slope of the perpendicular line is -1/m In this case as the slope, m, is 13 the slope of the perpendicular is -1/13 or -0.07692307692
If the slope is -3 what is the slope of the other line?
if there parallel its -3 but if there perpendicular the other lane must be positive:D
What makes two linear equations either parallel or perpendicular to each other?
Depending on the value of the slope or gradient if its the same then they are parallel if its a reciprocal then they are perpendicular.
