I believe they have Negative Slopes as stated by my Geometry Book. "Perpendicular Lines Have Slopes Which Are Negative ___"
There is no relationship between the slopes of parallel or perpendicular lines and their y-intercepts.
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.
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.
Negative reciprocals of one another.
If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.
Slopes of line perpendicular to the x-axis are undefined.
The slopes of perpendicular lines are reciprocals of each other. For example. if one line had an equation like y= 2x+4 then the perpendicular's slope would be y=x/2+4 -- they are reciprocals of each other.

Negative reciprocal slopes always represent perpendicular lines.
They are perpendicular if the product of their slopes is -1.
There is no relationship between the slopes of parallel or perpendicular lines and their y-intercepts.
Actually it IS. perpendicular lines have opposite reciprocal slopes and parallel lines have the same slope.
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.
The slopes of two perpendicular lines are negative inverses of each other. In other words, the two slopes when multiplied together equal -1.
