Segment AB is on the line y − 4 = −5(x − 1), and segment CD is on the line y − 4 = one fifth(x − 5).
Which statement proves the relationship of segments AB and CD?
A) They are perpendicular because they have slopes that are opposite reciprocals of 5 and negative one-fifth.
B) They are perpendicular because they have slopes that are opposite reciprocals of −5 and one-fifth.
C) They are parallel because they have the same slope of 5.
D) They are parallel because they have the same slope of negative one-fifth.
