Find the least-squares line given the matrix products $$ A^{T} A=\left[\begin{array}{cc}4 & 40 \ 40 & 494\end{array}ight] $$ and $$ A^{T} \mathbf{b}=\left[\begin{array}{c}1196.0 \ 13838.0\end{array}ight] $$

The least-squares line is $$ y = 99 + 20x $$.

Find the least-squares line given the matrix products \( A^{T} A=\left[\begin{array}{cc}4 & 40 \\ 40 & 494\end{array}\right] \) and \( A^{T} \mathbf{b}=\left[\begin{array}{c}1196.0 \\ 13838.0\end{array}\right] \)
