\section{Problem 1}

\subsection{Statement of the Problem}
A biologist is studying how fast the root of a particular specises of plant
grows. The results of one experiment are below. The biologist believes that the
`law' of root growth is 
$$ \text{Growth}=m\times\text{Days}, $$
and has asked us to determine the value of $m$ from the experimental data.

\begin{center}
\begin{tabular}{|c|c|}
\hline
\textbf{Day} & \textbf{Growth (mm)}\\\hline
0 &0\\
1 & 1.2\\
2 & 3.8\\
3 & 4.2\\
4 & 6.3\\
5 & 7.2\\
6 & 7.3\\
\hline
\end{tabular}
\end{center}

\noindent\textbf{Instructions}
\begin{enumerate}
\item Plot these points on the graph paper provided.
\item Draw a straight line that goes through the origin, and is as close to the other points as possible.
\item Calculate the slope of the line
\end{enumerate}
