Question

calcular o coeficiente angular das retas
A(3,-5) B(2,-2)

Answer 1

Oi Vanessa,

por $\Large\boxed{m= \dfrac{y-y_o}{x-x_o}}$

Podemos achar o coeficiente angular, onde:

$\begin{cases}y=-2\\ y_o=-5\\x=2\\x_o=3\\m=? \end{cases}$

Vamu lá então:

$m= \dfrac{-2-(-5)}{2-3}\\\\\\ m= \dfrac{-2+3}{-1}\\\\ \huge\boxed{m=1}$

Tenha ótimos estudos ;P
