Which of the following equations is an example of inverse variation between the variables x and y?
A. y= 3x
B. Y=3/x
C. y = x + 3
D. Y=x/3

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
