I think it’s A. Hope it’s right. Sorry if it’s wrong.
Yes, these both are direct relationships and can be written like
, where k is the constant of variation.
For the first equation, k = 10. For the second equation, k = -4/3. You find it by rearranging the equation into the form
, and you use the coefficient of x for k.
