Write in y=mx+b Form -4x+4y+4=0

$- 4 x + 4 y + 4 = 0$

Step 1

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Step 2

Rewrite in slope-intercept form.

Move all terms not containing $y$ to the right side of the equation.

Add $4 x$ to both sides of the equation.

$4 y + 4 = 4 x$

Subtract $4$ from both sides of the equation.

$4 y = 4 x - 4$

Divide each term in $4 y = 4 x - 4$ by $4$ and simplify.

Divide each term in $4 y = 4 x - 4$ by $4$ .

$\frac{4 y}{4} = \frac{4 x}{4} + \frac{- 4}{4}$

Simplify the left side.

Cancel the common factor of $4$ .

Cancel the common factor.

$\frac{4 y}{4} = \frac{4 x}{4} + \frac{- 4}{4}$

Divide $y$ by $1$ .

$y = \frac{4 x}{4} + \frac{- 4}{4}$

Simplify the right side.

Simplify each term.

Cancel the common factor of $4$ .

Cancel the common factor.

$y = \frac{4 x}{4} + \frac{- 4}{4}$

Divide $x$ by $1$ .

$y = x + \frac{- 4}{4}$

Divide $- 4$ by $4$ .

$y = x - 1$
