    okay, the lines are parallel if the slopes are the same. is -3 equal to -3/5?

    okay, the two slopes are not the same. there fore the two lines are not parallel. now, what is the condition for two lines to be perpendicular?

    their slope are negative reciprocal of each other

    no, try again. if x is your number, -(1/x) is its negative reciprocal

    so if -3 is your number, what is its negative reciprocal?

    -1/3

    no! it is -(1/(-3)) = 1/3. so, is 1/3 equal to -3/5?

    so then the lines are not perpendicular. So your answer is the lines are neither parallel nor perpendicular to each other.
