Question

Dado os pontos A(-1,3)e B(0,5) encontre o coeficiente linear da reta que passa pelos mesmos

Answer 1

Olá !

Calculando o coeficiente angular ...

$\mathsf{m=\dfrac{\Delta_{y}}{\Delta_{x}}} \\\\\\ \mathsf{m=\dfrac{(y_{B}-y_{A})}{(x_{B}-x_{A})}} \\\\\\ \mathsf{m=\dfrac{(5-3)}{(0-(-1)}} \\\\\\ \mathsf{m=\dfrac{2}{1}} \\\\\\ \boxed{\mathsf{m=2}}$

$\textbf{RESPOSTA~~:}$

O coeficiente angular é 2.
