@theopenstudyowl could you help me?

Answer 2

i can try

Answer 3

i'm not good at the one you were assigned to. i'm sorry :/

Answer 4

My solution: The term "direct variation" is exactly the contrary of "inverse variation." Generally direct variation is expressed with y=kx, where k is the constant, while inverse variation is denoted as y = k/x, where k is also the constant. For this problem, i would have to say that the answer would have to be an answer that has the slope of -3. So we can rule out a since it's slope the reciprocal of -3, and b since it does not really have anything to do with slope. I would personally pick d since a function that has the same slope is always linear to the original equation. However, that is assuming that this graph is of an equation that is a straight line which has a constant slope. So through the process of elimination, I would conclude the answer is d.
