anonymous · Answer

oh gots it

nnesha · Answer

yes equation for direct variation is y = kx 
replace x and y by their values y = 10 and x = -3
then solve for k like wer did on previous post

anonymous · Answer

would it be A because the answer was .3 ?

nnesha · Answer

nope

nnesha · Answer

btw look at ur answer chocies 
are you sure u they are right ??
