#### Explanation:

$\text{Slope formula knowing two points on the line }$

$m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

$\text{Given : } \left({x}_{1} , {y}_{1}\right) = \left(4 , - 5\right) , \left({x}_{2} , {y}_{2}\right) = \left(- 1 , - 5\right)$

$m = \frac{- 5 + 5}{- 1 - 4} = \frac{0}{-} 5 = 0$
