Question

obtenha a equação resolvida de cada uma das retas abaixo e, em cada caso, identifique o coeficiente angular e coeficiente linear.
​

Answer 1

a)

$\mathsf{5x-y+3=0\to~y=5x+3}\\\mathsf{coeficiente\,angular:5~~coeficiente~~linear:3}$

b)

$\mathsf{2x+3y-7=0\to~3y=-2x+7\to~~y=\dfrac{-2x+7}{3}}\\\mathsf{coeficiente\,angular:-\dfrac{2}{3}~~coeficiente\,linear:\dfrac{7}{3}}$

c)

$\mathsf{x-2y+4=0\to~2y=x+4\to~y=\dfrac{x+4}{2}}\\\mathsf{coeficiente\,angular:\dfrac{1}{2}~~coeficiente\,linear:2}$

d)

$\mathsf{6x+3y-1=0\to~3y=-6x+1\to~y=\dfrac{-6x+1}{3}}\\\mathsf{coeficiente\,angular:-2~~coeficiente\,linear:\dfrac{1}{3}}$
