Parallel lines have the same slope.
Perpendicular lines have slopes that are negative reciprocals of each other.

for specific! in parallel traces the slopes are the comparable. Guessing: in perpendicular traces the slopes must be the unfavorable inverse of one yet another. e.g. a line with the slope of four/3 the different line ought to have a slope of -3/4 to be perpendicular.

I don't know if this will make sense to you but if the slope of two lines is the same, they are parallel lines
If the slope of two lines are the opposite, they are perpendicular lines
For example two lines with the same slope of 3 are parallel
And if one line has something like a 3 and the other line has the slope of something like a -1/3, they are perpendicular
I don't know of you understand now but I hope this helps! =)

Parallel lines have the same slope.
Perpendicular lines have negative-reciprocal slopes. That it if one line has slope m, the perpendicular line has slope -1/m.

If two lines are parallel, they have the same slope.
y = 3x -5
y = 3x +27
y = 3x +25,006
are parallel.
If two lines are perpendicular, the second slope is -1/the first
y = 3x - 5
y = -1x/3 +27
are perpendicular
If two lines are parallel, they will always be perpendicular to the same set of lines.
If line AB and CD are parallel and AB is perpendicular to EF, then CD is perpendicular to EF.
