3x+6y=-12 slope intercept form?

y = - 1/3x - 2

Step-by-step explanation:

3x+6y=-12

-3x - 3x

6y = - 3x - 12

/6 / 6

y = - 3/6x - 2

y = - 1/3x - 2

y = - 1/2x - 2

Step-by-step explanation:

Slope-intercept form is y=mx+b. m = slope and b=y-intercept.

Subtract 3x from both sides of the equation.

Divide each term by 6 then simplify.

6y/6 = - 3x/6 - 12/6

Cancel out the common factors

y = - 3x/6 - 12/6

Simplify

y = - x/2 - 2

Answer:

y = - 1/2x - 2
