The slope is zero
Explanation:The given points: (2, -3) and (-4, -3)
we apply the slope formula:
[tex]\begin{gathered} m\text{ = }\frac{y_2-y_1}{x_2-x_1} \\ x_1=2,y_1=-3,x_2=-4,y_2\text{ = }-3 \end{gathered}[/tex][tex]\begin{gathered} m\text{ = slope = }\frac{-3-(-3)}{-4-2} \\ =\text{ }\frac{-3+3}{-6} \end{gathered}[/tex][tex]\begin{gathered} \text{slope = m = }\frac{0}{-6} \\ \text{slope = 0} \end{gathered}[/tex]Hence, the slope is zero
