Answer 1

Answer:

-9/8

Step-by-step explanation:

m=y2-y1/x2-x1

9-18=(-9)

9-1=8

-9/8

hope this helps :3

if it did pls mark brainliest

Answer 2

Answer:

Step-by-step explanation:

(x₁, y₁ )  = (1 , 18 )          &   (x₂ , y₂) = ( 9 , 9)

$Slope =\frac{y_{2}-y_{1}}{x_{2}-x-{1}}$

        $= \frac{9 - 18}{9 - 1}\\\\\\= \frac{-9}{8}$
