Use the given data to find the equation of the regression line. Round the final values to three significant digits, if necessary.
-$\begin{array}{c|ccccc}
x & 6 & 8 & 20 & 28 & 36 \
\hline \mathrm{y} & 2 & 4 & 13 & 20 & 30
\end{array}$

A) $\hat{y} = - 3.79 + 0.897 x$
B) $\hat { y } = - 3.79 + 0.801 x$
C) $\hat{y} = - 2.79 + 0.950 x$
D) $\hat{y} = - 2.79 + 0.897 x$
