What is the slope of the line passing through the point (3, −4) and perpendicular to the line y = 3x + 5? Write your answer as a fraction.

Question

anonymous · Answer

so u have point (3,-4) and the gradient of the perpendicular line is gonna be -1/gradient of the line y=3x+5 so -1/3 .. 
use y-y1=m(x-x1) to find equation of perpendicular line

anonymous · Answer

so y-(-4)=m(x-3)?

hartnn · Answer

isn't product of slopes of two perpendicular lines=-1.....and answer simply be -1/3??

anonymous · Answer

idk thats why I'm asking.

anonymous · Answer

anyone know the answer to this???

anonymous · Answer

oh my bad .. its just asking for slope of the line .. thought it was asking for equation

anonymous · Answer

no just the slope

anonymous · Answer

know how to find the slope of this @powerangers69 ?

anonymous · Answer

um for 2 linear lines to be parallel their gradients m1xm2=-1 so u have m1 just sub that in and solve for m2 which is slope of perpendicular line

anonymous · Answer

so it would be -1/3?

anonymous · Answer

yeah
