Answer:
[tex]\huge\boxed{slope=-\dfrac{3}{2}}[/tex]
Step-by-step explanation:
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have two points (-6, -8) and (-14, 4).
Substitute
[tex]x_1=-6,\ y_1=-8,\ x_2=-14,\ y_2=4[/tex]
[tex]m=\dfrac{4-(-8)}{-14-(-6)}=\dfrac{4+8}{-14+6}=\dfrac{12}{-8}=-\dfrac{12:4}{8:2}=-\dfrac{3}{2}[/tex]
