Question

escreva as funções na forma y=ax+b e determine os valores dos coeficientes a e b de cada uma delas .a.4y-3x+2=-y-4x-7. b.-2x-x+3=4y-6x-1

Answer 1

a) $4y-3x+2=-y-4x-7$

$4y+y=-4x+3x-7-2$

$5y=-x-9$

$y=- \dfrac{1}{5} x- \dfrac{9}{5}$

$a= -\dfrac{1}{5}$

$b= -\dfrac{9}{5}$

b) $-2x-x+3=4y-6x-1$

$-4y=-6x+2x+x-1+3$

$-4y=-3x+2$

$4y=3x-2$

$y= \dfrac{3}{4} x- \dfrac{2}{4}$

$y= \dfrac{3}{4} x- \dfrac{1}{2}$

$a= \dfrac{3}{4}$

$b= \dfrac{1}{2}$
