Question

considerando a equação geral da reta, determine o coeficiente angular e linear:
a) x+y=0
b) 3x-4y+3=0

Answer 1

Olá,

o coeficiente angular é o termo (b), e o linear, o (c), na equação do tipo y=ax+b, portanto façamos..

A)

$x+y=0\\ y=-x+0\\ ~~~~~~~~~|~~~~~|\\ ~~~~coef.~~~coef\\ angular~~~linear$

B)

$3x-4y+3=0\\ 3x+3=4y\\\\y= \dfrac{3x+3}{4}\\\\ y= \dfrac{3}{4}x+ \dfrac{3}{4}\\ ~~~~~~~|~~~~~~~|\\ ~~~~coef.~~coef.\\ angular~~linear$

Tenha ótimos estudos ;D

Answer 2

$a) y= - x; C_{angular} = -1; Linear=0.$$b)3x + 3= 4y--\ \textgreater \ y = \frac{3x}{4}+ \frac{3}{4} ; C_{angular} = \frac{3x}{4} ; Linear = \frac{3}{4} .$
