Answer:
D. y=4x
Explanation:
It asks for a proportional relationship between x and y
And is the only answer
because
When x and y is 1 the answer is
4/1
And when x and y is 2 the answer is
8/2
If you divide both of them are still 4
And this will always be the result no matter how many times you do it
like if you put it as 150
150 times 4 is 600/150
600 divided by 150 is 4
Hope this helps!
