$S l o p e = - \frac{3}{2}$

Explanation:

Line passing through the points are-$R \left(12. - 7\right)$ and $S \left(- 6 , - 4\right)$.

R ≡(12,-7) ≡ (x_1,y_1)

S ≡(-6,-4) ≡ (x_2,y_2)

$S l o p e = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

$S l o p e = \frac{- 4 - \left(- 7\right)}{- 6 - \left(- 4\right)}$

$S l o p e = \frac{- 4 + 7}{- 6 + 4}$

$S l o p e = \frac{3}{-} 2$

$S l o p e = - \frac{3}{2}$
