Question

Find the slope of the lines that passes through (10,3) and (1,2)

Answer 1

`\bold{m=\frac19=1.\overline1}`

Explanation:

`\bold{slope\, (m)=(change\ in\ Y)/(change\ in\ X)=(y_2-y_1)/(x_2-x_1)}`

(10, 3) ⇒ x₁ = 10, y₁ = 3

(1, 2) ⇒ x₂ = 1, y₂ = 2

So the slope:

`\bold{m=(2-3)/(1-10)=(-1)/(-9)=\frac19=1.\overline1}`
