Answer:
Yes, the relationship is proportional.
Explanation:
So if you don't understand what proportional means, it means corresponding, the same, equal.
So when you look at a graph like this then ask yourself this, "is x a multiple of y?"
For example: Is 2 a multiple of 4? Yes! It is! That makes it proportional.
Is 3 a multiple of 9? Yes it is! 3, 6, 9.
Is 4 a multiple of 12? It is 4, 8, 12
