The product of the slopes of two non-vertical perpendicular lines is always -1. it is not possible for two perpendicular lines to both have a positive slope because the product of two positives is positive. so for the product of the slopes to be -1, one of the slopes must be positive and the other negative. select the best answer from the choices provided
true or false

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
