Question

Is `-7x=-56y` a direct variation equation and if so, what is the constant of variation?

Answer 1

`k=1/8`

Explanation:

`"a direct variation equation has the form"`

`•color(white)(x)y=kxlarrcolor(blue)"k is the constant of variation"`

`-7x=-56y`

`rArry=(-7)/(-56)x`

`rArry=1/8xlarrcolor(blue)"direct variation"`

`rArrk=1/8`
