# For the equation #-4y=8x#, what is the constant of variation?

##### 1 Answer

The constant of variation is

#### Explanation:

We can solve this equation for

#-4y=8x#

#color(white)(-4)y=(8x)/-4#

#color(white)(-4y)=-2x#

Now we have an equation that says, "*this*

Can we show this?

Let *constant of variation* of

#y^star = -2x^star#

Which means

#y^star = -2(x+1)" "# (since#x^star = x+1# )

#color(white)(y^star) = -2x-2#

But wait,

#y^star = y - 2#

And there we go! When *less than*
