is this parallel or perpendicular y=4x+5 and y=-1/4x+4
It would be I think perpendicular but don't take my word on it cuz I might be wrong....
y=mx+bm=slopeparalelll ines have slopes that multiply to -1first one is y=4x+5, slope is 42nd one is y=-1/4x+4, slope is -1/44≠-1/44 times -1/4=-1they are perpendicular
