Hi there!

So first off, here are little definitions you need to know in order to be able to answer your question :

<u>Constant</u> means that the rates of change are the same.

<u>Variable</u> means that the rates of change are different.


But from what I can see, you don't even need those definitions because you got both answers right!


Continue your great work! If there's anything just let me know! :)
