perl · Answer

8x + 6y = -5  , is that the equation?

anonymous · Answer

yes it is

perl · Answer

ok first solve for y ,

perl · Answer

after you solve y = mx + b, 
the slope of the perpindicular line will be -1/m

anonymous · Answer

i think it y=-8/6-5 but i dont know im terrible

perl · Answer

almost

anonymous · Answer

y=-8/6x-5*

anonymous · Answer

ive been trying to do this on my own but i cant

perl · Answer

8x + 6y = -5

6y = -8x -5

y = -8/6x - 5/6

perl · Answer

or in lowest terms
y = -4/3x - 5/6

anonymous · Answer

So how do i find the perpendicular line?

perl · Answer

after you solve y = mx + b, the slope of the perpindicular line will be -1/m

perl · Answer

the negative reciprocal

anonymous · Answer

so the slope would be 3/4x?
