Question

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

Answer 1

Answer:

        m = -2

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:

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