Answer 1

Remember to calculate a slope it is rise divided by run, or (y₂ - y₁ )/(x₂ - x₁) or in your case (2-8))/(-9-9) or -6/-18 or 1/3. 

Answer 2

Hi Mikk;

Slope is calculated as change-of-y divided by change-of-x...

(y-y₁)/(x-x₁)

(8-2)/(9--9)

Subtracting a negative number is the same as adding a positive number...

(8-2)(9+9)

6/18

1/3
