Use the given data to find the equation of the regression line. Round the final values to three significant digits, if necessary.
-$\begin{array}{l|lllll}
\mathrm{x} & 0 & 3 & 4 & 5 & 12 \
\hline \mathrm{y} & 8 & 2 & 6 & 9 & 12
\end{array}$

A) $\hat { y } = 4.98 + 0.725 x$
B) $\hat { y } = 4.88 + 0.625 x$
C) $\hat { y } = 4.98 + 0.425 x$
D) $\hat { y } = 4.88 + 0.525 x$
