Question

Dada as equações abaixo, determine os valores de a e b: a) y = 6 x + 3 b) y = – 5 x + 2 c) y = – 2 x – 4 d) y = 4 x – 1

Answer 1

a) y = 6x + 3

0 = 6x + 3

- 6x = 3

x =

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

b) y = - 5x + 2

0 = - 5x + 2

5x = 2

x =

$\frac{2}{5}$

c) y = - 2x - 4

0 = - 2x - 4

2x = - 4

x = - 2

d) y = 4x - 1

0 = 4x - 1

- 4x = - 1

x =

$\frac{1}{4}$
