Question

The relationship between the height of a tree and the time since the tree was planted?

Answer 1

The relationship shows the growth rate and acceleration throughout that certain time period.  In other words, the two put together to create a relationship of a unit rate when simplified.

Answer 2

It´s correlated.

Explanation:

The graph shows that the height of the tree increases as time passes, meaning that the more time that a three has been planted the more height it has, so there´s a direct correlation between the time passing and the height of the tree.
