2... 3x+2y=4
x+2y=-4

3... 4x+y=1
x+y=-2

Answer 1

Below.

I Hope it helps :)

Explanation:

Slope intercept form :

y=mx+b

1.

`2x + y = 1`

Slope intercept form :

`y = - 2x + 1`

Equation :

`x - 2y = 8`

Slope intercept form :

`- 2y = - x + 8`

or

`y = (1)/(2) x - 4`

2.

`3x + 2y = 4`

Slope intercept form :

`2y = - 3x + 4 \\`

Divide through by 2

`y = - (3)/(2) x + 2`

Equation :

`x + 2y = - 4`

Slope intercept form :

`2y = - x - 4`

Divide through by 2

`y = - (1)/(2) x - 2`

3.

`4x + y = 1`

Slope intercept form =

`y = - 4x + 1`

Equation :

`x + y = - 2`

Slope intercept form :

`y = - x - 2`
