Question

for the equation -4y=8x what is the constant of variation

Answer 1

It would be -2 because the equation for the constant variation is y=kx k being the constant variation so you just put the equation in constant cariation form
-4y=8x
-4/(-4y)= -4/(8x)
y=-2x
y=kx
which means that k (constant variation) is -2 :D

Answer 2

oh ok thanks :)
