What is meant by "aligning the data" in the context of the table of values below:

$\backslash$table$[[$Year$,$Sales $($quadrillion kWh $)],[2003,1\mathrm{.}20],[2004,1\mathrm{.}23],[2005,1\mathrm{.}27],[2006,1\mathrm{.}30],[2007,1\mathrm{.}33],[2008,1\mathrm{.}35]]$

We find a linear model for the retail sales $t$ years after $2000.$

$($If you need help with this, refer to the third video in Step $1$ of the module for $1\mathrm{.}4.)$

We will enter the values $t=2003,2004,2005,$dots into L $1$ of our calculator.

This is a trick question, there is no such thing as "aligning data".

We will make sure the calculator gives us a line.

We will enter $t=0,1,2,3,$dots into L $1$ of our calculator.

We will enter the values $t=3,4,5,$dots into L $1$ of our calculator.

We will make sure we have the same number of values in L$1$ as we do in L$2.$
