Write the equation of a line in slope-intercept form that is perpendicular to the line y=3/5x-1 and passes through the point (-9, 4).

OpenStudy (anonymous):

what is the slope of a perpendicular line?

OpenStudy (anonymous):

i dont know thts all i have and im confused

OpenStudy (anonymous):

it's the negative reciprocal.

OpenStudy (anonymous):

-9

OpenStudy (anonymous):

negative reciprocal of 3x/5 is not -9

OpenStudy (anonymous):

then?

OpenStudy (anonymous):

y=mx+b where m is the slope. Since the perpendicular slope is the negative reciprocal, you flip the fraction representing the slope and you multiply it by -1.

OpenStudy (anonymous):

so would it be -5/3x-11
