(-1, 3) and perpendicular to y = -1/3x + 7. y = 3x - 12 y = 3x + 6 y = 3x - 6 y = 3x

do u know when two lines are perpendicular?

OpenStudy (anonymous):

yea dont they just keep going and have the same slope ohh duh so it would be y=3x right

OpenStudy (angela210793):

no...two lines are perpendicular when the slope of one is the negative reciprocal of the other so |dw:1345560045065:dw| what is the slope of the line given?
