You can put this solution on YOUR website!
well if they are perpendicular they will have the opposite slope and if they are parralell they with have the same slope, if neither then there slopes are completely different.
so y=mx%2Bb put both equations in this form
y%2B20=-4x
y=-4x-20 m=-4%2F1
4y=24x-14
y=6x-%287%2F2%29 m=6
so the answer is neither
for them to be parralel they have to be like: -4%2F1 and -4%2F1
for them to be perpendicular they have to be like: -4%2F1 and 1%2F4
