R value
We have that a correlation coefficient shows us how related is the dependent variable to the behavior of the independent variable.
Magnitud
A correlation coefficient of ±1 means that the dependent variable moves as the independent variables moves too.
0 means that the dependent variable can move or not no matter how the independent variable changes.
As ±0.89 is near to ±1, we can say that in this case dependent and independent variable are related.
Sign
When the coeffitcient of correlation is negative it means that if the independent variable goes up, the dependent goes down, and visceversa.
In this case, while one decreases the other increases.
Answer: as the independent value increases, the dependent value decreases.
