HELP FAST =For the equation -4y = 8x, what is the constant of variation?A)-4B)-2C)1D)3

Answer 1

A proportional relationship is given by the expression:

y=kx, where k is the constant of variation

Then, in this case, isolating the variable y

y=-8/4x

y=-2x

The constant of variation would be k=-2
