-(1/3)
If the lines have the same slope but with different y intercepts then they are parallel
The slope of a perpendicular line is not defined.
No but if the two lines are parallel then they will have the same slope.
They are negative reciprocals. So if the slope of a line is x, the slope of the perpendicular line is -1/x
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
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
No, lines have the same slope if and only if they are parallel to each other.
If the lines have the same slope but with different y intercepts then they are parallel
The slope of a perpendicular line is not defined.
You have to know the slopes of both lines. -- Take the two slopes. -- The lines are perpendicular if (one slope) = -1/(the other slope), or the product of the slopes equals to -1.
The slope of parallel lines are the same, but the slope of perpendicular lines are negative reciprocals of each other.
For any two perpendicular lines (save a vertical and a horizontal one), the product of their slopes is always -1. For two perpendicular lines with one having a slope of -2, the other will have a slope equal to -1 divided by -2, which equals 1/2.
The straight line equation is y = mx + b. If they do not cross and have the same slope they are parallel; if they cross and the slope (m) of one of them is the negative inverse slope of the other (-1/m) they are perpendicular. Otherwise they are neither
No because two lines with the same slope but with different y intercepts are parallel lines. Perpendicular lines meet each other at right angles.
Perpendicular lines have slopes that the inverse of each other. If one line has a slope of 1/3, the other has a slop of 3/1
No but if the two lines are parallel then they will have the same slope.
They are the negative reciprocal of each other. Fo rexample, if a line has slope = +2, then the line perpendicular to it has slope -1/2
