What type of relationship does y=2x have

I would assume that the answer to this question would be either a direct relationship which means as X increases, y increases. The other option would be an indirect relationship where as X increases, y decreases.
If you choose to increasing values for x and substitute that into the equation, you will find that the Y values also increase.
x y
1. 2
2. 4
3. 6
This means that those two variables have a direct relationship
