QUICK! What is the slope of a perpendicular for y - 7x - 2

OpenStudy (anonymous):

y = 7x - 2***

OpenStudy (anonymous):

if it were parallel it would be y = 7x - 2 but what would the perpendicular be?

OpenStudy (ajprincess):

what is the slope of the line y=7x-2?

OpenStudy (ajprincess):

the product of the slopes of perpendicular lines = -1. if the slope of the given line is m_1 and the slope of the required line is m_2 then m_1*m_2=-1
