Answer:
[tex]m=0[/tex]
Step-by-step explanation:
Given the points
(-8,-3)and(-12,-3)
The slope between the points (-8,-3) and (-12,-3) can be determined
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-8,\:-3\right),\:\left(x_2,\:y_2\right)=\left(-12,\:-3\right)[/tex]
[tex]m=\frac{-3-\left(-3\right)}{-12-\left(-8\right)}[/tex]
[tex]m=0[/tex]
