Answer:
[tex]\bold{m=\dfrac19=1.\overline1}[/tex]
Step-by-step explanation:
[tex]\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
(10, 3) ⇒ x₁ = 10, y₁ = 3
(1, 2) ⇒ x₂ = 1, y₂ = 2
So the slope:
[tex]\bold{m=\dfrac{2-3}{1-10}=\dfrac{-1}{-9}=\dfrac19=1.\overline1}[/tex]
