Write an equation of a line in point slope form that is perpendicular to y=3x-7 and goes through (6,8)

OpenStudy (stefrheart):

so first what is the perpendicular slope going to be?

OpenStudy (anonymous):

-3?

OpenStudy (stefrheart):

close! its -1/3 because the perpendicular slope has to be the opposite reciprocal Next you have to make the point slope form

OpenStudy (anonymous):

Y-8=-1/3(x-6)

OpenStudy (stefrheart):

yes! now you have the answer!

Thanks so much
