Which representation shows a non proportional relationship between x and y?

D.

Step-by-step explanation:

If the  value of y/x is the same for the given data  it is proportional. From a graph we see  its proportional if its a straight line passing through the origin.

So  A is proportional.

Also  equations of the form y = kx where k is a constant are proportional ( Choice B).

The answer is D because if we check 2 of the rows:

 y/x = 3/5 = 0.6  for the last row and y/x is different

(y/x = 1.8 / 2 = 0.9) for the previous row.

For choice C,  y/x values are constant.

sine
