y=-x-4
as this is in the form of y=mx+b, the slope of this line is -1.
5x + 5y = 20
x + y = 4
y = -x + 4
the slope of this line is -1.
Since the slope of each of the two lines are the same (-1) they are in fact parallel to each other, not perpendicular.
I believe they have Negative Slopes as stated by my Geometry Book. "Perpendicular Lines Have Slopes Which Are Negative ___"
The slopes of perpendicular lines are negative reciprocals.[ y = -3x + 2 ] is perpendicular to [ y = x/3 plus any number ].
If you have two lines that have negative recipricals (1 and -1 for example), the lines are perpendicular.
The slope of parallel lines are the same, but the slope of perpendicular lines are negative reciprocals of each other.
They are perpendicular if their slopes are mutual negative reciprocals.
Are perpendicular.

Negative reciprocal slopes always represent perpendicular lines.
