Explanation:
Use the point-slope form of a linear function, which is represented by the following equation;
![\begin{gathered} y-y_0=m(x-x_0) \\ where, \\ (x_0,y_0)\text{ is the given point} \\ m=\text{ slope} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/envrohoiel7r6ei03vgndc0c8i0pjud618.png)
Therefore, if the line passes through the point (-8,-4) and has zero slope:
![\begin{gathered} y+8=0(x+4) \\ y=-8 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/bd8e6xjyhllqqjzdl9ysd04weyxon5jtnf.png)
The line is horizontal therefore the line equation is y=-8.
