An experiment was conducted to determine if the weight of an animal can be predicted after a given period of time on the basis of the initial weight of the animal and the amount of feed that was eaten. The following data, measured in kilograms, were recorded:
\(\begin{array}{ccc}
\begin{array}{c}
\text { Final } \\
\text { Weight, } \boldsymbol{y}
\end{array} & \begin{array}{c}
\text { Initial } \\
