Answer 1

positive nonlinear

Explanation:

Answer 2

Positive nonlinear association

Explanation:

The correlation coefficient is fairly low at 0.28, so there is a positive association, but it is definitely not linear.

(It may not be fair to call it non-linear, either. There seems to be no specific value of correlation coefficient below which you declare there to be "no association.")
