Question

What is the slope of the line that passes through the points (-5,7) and
(10, 1)?

Answer 1

`\bold{m=-\frac25}`

Explanation:

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

(-5, 7) ⇒ x₁ = -5, y₁ = 7

(10, 1) ⇒ x₂ = 10, y₂ = 1

So the slope:

`\bold{m=(1-7)/(10+5)=(-6)/(15)=-\frac25}`
