$- 8 x - 2 y = - 26$

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.

Step 2.1

Add $8 x$ to both sides of the equation.

$- 2 y = - 26 + 8 x$

Step 2.2

Step 2.2.1

Divide each term in $- 2 y = - 26 + 8 x$ by $- 2$ .

$\frac{- 2 y}{- 2} = \frac{- 26}{- 2} + \frac{8 x}{- 2}$

Step 2.2.2

Step 2.2.2.1.1

Cancel the common factor.

$\frac{- 2 y}{- 2} = \frac{- 26}{- 2} + \frac{8 x}{- 2}$

Step 2.2.2.1.2

Divide $y$ by $1$ .

$y = \frac{- 26}{- 2} + \frac{8 x}{- 2}$

Step 2.2.3

Simplify the right side.

Step 2.2.3.1.1

Divide $- 26$ by $- 2$ .

$y = 13 + \frac{8 x}{- 2}$

Step 2.2.3.1.2

Cancel the common factor of $8$ and $- 2$ .

Step 2.2.3.1.2.1

Factor $2$ out of $8 x$ .

$y = 13 + \frac{2 (4 x)}{- 2}$

Step 2.2.3.1.2.2

Move the negative one from the denominator of $\frac{4 x}{- 1}$ .

$y = 13 - 1 \cdot (4 x)$

Step 2.2.3.1.3

Rewrite $- 1 \cdot (4 x)$ as $- (4 x)$ .

$y = 13 - (4 x)$

Step 2.2.3.1.4

Multiply $4$ by $- 1$ .

$y = 13 - 4 x$

Step 2.3

Reorder $13$ and $- 4 x$ .

$y = - 4 x + 13$
