Isaac Ellison · Answer 1

The answer would be: D. y = 10x

The value of y is 30 when x is 3. Then, the ratio of y:x would be: 30/3=10

That means Y would be 10 times more than X. Then, the right choice would be: y = 10 x

You can check it by inserting the number (y=30. x=10) like this:

y = 10 x

30 = 10 (3)

30 = 30
