For the given data, which equation would best represent the line of best fit?
\begin{array}{|c|c|c|c|c|c|c|c|c|c|}
\hline x & .8 & 1.5 & 2 & 2.1 & 2.7 & 2.8 & 3.3 & 4.1 & 5 \\
\hline y & 10.1 & 6.9 & 8 & 6.4 & 7 & 6.1 & 4.9 & 3.9 & 1.5 \\
\hline
\end{array}
\(y=1.8x+11.0\)
\(y=-1.8x+11.0\)
\(y=1.8x-11.0\)
