Example 2:

The values of x and their corresponding values of y are shown in the table below:

$$\begin{array}{c|ccccc} X & ~1~ & ~2~ & ~3~ & ~4~ & ~5 \\ Y & ~4~ & ~8~ & ~9~ & ~11~& ~16 \end{array}$$

a) Find the least square regression line in the form $~~y = a \cdot x + b$.

b) Plot the given points and the regression line.
