Determine if the lines r and s are parallel A) since both lines have a slope of __, lines r and S are parallel

B) the slope of line r is __, and the slope of line s is __. Since the product of their slopes is -1, lines r and s are parallel.

C) the slope of line r is __, and the slope of s is __. Since the product are different, Ines r and s are not parallel

D) the slope of line r is __, and the slope of line s is __. Since the product of their slopes is not -1, lines r and s are not parallel

Please simplify answer, anyone who does answer thank you! :)
