Two lines with the same slope are parallel.
The slope of a perpendicular line is not defined.
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
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
No but if the two lines are parallel then they will have the same slope.
No because two lines with the same slope but with different y intercepts are parallel lines. Perpendicular lines meet each other at right angles.
They are negative reciprocals. So if the slope of a line is x, the slope of the perpendicular line is -1/x
No, lines have the same slope if and only if they are parallel to 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.
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.
When the lines are horizontal and vertical. (slope of zero) (undefined slope)
Actually it IS. perpendicular lines have opposite reciprocal slopes and parallel lines have the same slope.
