*In this task, refer to the system of normal equations and the formulas for $a$ and $b$ given on page $877$.* If $$ \overline{x}=\frac{1}{n}\sum\limits_{k=1}^n x_k\qquad\text{and}\qquad\overline{y}=\frac{1}{n}\sum\limits_{k=1}^n y_k $$ are the averages of the $x$ and $y$ coordinates, respectively, show that the point $(\overline{x}, \overline{y})$ satisfies the equation of the least squares line, $y=ax+b$.
