A) y = -3x-1
B) .y = 4x+2
C) .y = 3x-2
D) .y = 5x+1

Me ajudem aí,pff​

Answer 1

a)

$y = - 3x - 1$

$0 = - 3x - 1$

$3x = - 1$

$x = - \frac{1}{3}$

b)

$y = 4x + 2$

$0 = 4x + 2$

$- 4x = 2$

$x = - \frac{1}{2}$

c)

$y = 3x - 2$

$0 = 3x - 2$

$- 3x = - 2$

$x = \frac{2}{3}$

d)

$y = 5x + 1$

$0 = 5x + 1$

$- 5x = 1$

$x = - \frac{1}{5}$
