You need to rewrite the given equations in standard form y = mx +b, where m is the slope.

First equation:

x + 2y = 0

Subtract x from each side:

2y = -x + 0

Divide both sides by 2:

y = -x/2 +0 = y = -1/2x +0

This give you a negative 1/2 slope

The first equation is the correct one.

Answer:

x + 2y = 0.

Step-by-step explanation:

Let's see what slope we get with the answer you gave:

- x + 2y = 0

Convert to slope/intercept form  ( y = mx + c).

- x + x + 2y = 0  + x   ( adding x to both sides of the equation).

2y = x

Divide both sides by 2:

y = 1/2 x  

That is the slope is 1/2.

Correct is x + 2y = 0:

2y = -x

y = -1/2 x
