Find the slope of the given points (3,4) and (7,-4)

mr Goodwill [35]

Answer:

<h2> m = -2</h2>

Step-by-step explanation:

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

(3, 4) ⇒ x₁ = 3, y₁ = 4

(7, -4) ⇒ x₂ = 7, y₂ = -4

So the slope:

$\bold{m=\dfrac{-4-4}{7-3}=\dfrac{-8}4=-2}$
