Question

obtenha a equaçao segmentária das equações da reta a seguir:

A- 7x-2y+42=0

B-9x+6y-18=0

Answer 1

Olá, Karolzinha.

$A)\,\,7x-2y+42=0\Rightarrow 7x-2y=-42\Rightarrow -\frac7{42}x+\frac2{42}y=1\Rightarrow\\\\ -\frac x{42/7}+\frac y{42/2}=1\Rightarrow \boxed{-\frac x 6+\frac y{21}=1}$

$B)\,\,9x+6y-18=0\Rightarrow9x+6y=18\Rightarrow\frac9{18}x+\frac6{18}y=1\Rightarrow\\\\ \frac{x}{18/9}+\frac{y}{18/6}=1\Rightarrow\boxed{\frac x 2+\frac y 3=1}$
