-  You should now be able to --
 \begin{itemize}
-\item Plot a least square fit line.
+\item Generate a least square fit using matrices.

+\item ~[1.0, 1.0, 1.0]~
+\item Error
+\end{itemize}

+\item The plot of ``u'' vs ``v'' is a bunch of scattered points that show a
+     linear trend. How do you find the least square fit line of ``u'' v/s ``v''.
