[tex]\begin{gathered} \text{The point are,} \\ x_1=-3, \\ y_1=-1, \\ x_2=-1, \\ y_2=-3 \end{gathered}[/tex]

The formula for equation od line is,

[tex]\begin{gathered} \frac{y-y_1}{y_2-y_1}=\frac{x-x_1}{x_2-x_1} \\ \frac{y-(-1)}{-3-(-1)}=\frac{x-(-3)}{-1-(-3)} \\ \frac{y+1}{-2}=\frac{x+3}{2} \\ 2y+2=-2x-6 \\ 2y=-2x-8 \\ y=-x-4 \end{gathered}[/tex]
