Doubt about significance of regression


Dear all,
In an excel file, we have temperature (te) and humidity (hu) data in two columns. The Gaussian kernel-density estimation and best-fit quadratic curve were plotted. However, we need to determine whether the relationship is statistically significant or not, as well as the coefficient of determination (R2). For calulation of the both of them, we used functions like:
1. cofficient of determination aa= fitlm(te, hu)
2. statistically significant p= coefTest(aa)
Is it correct? If not, please provide the any other suggestions.
Thank you.
