$20 + y + 8 x = 0$

Step 1

Rewrite in slope-intercept form.

Step 1.1

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 1.2

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

Step 1.2.1

Subtract $20$ from both sides of the equation.

$y + 8 x = - 20$

Step 1.2.2

Subtract $8 x$ from both sides of the equation.

$y = - 20 - 8 x$

Step 1.3

Reorder $- 20$ and $- 8 x$ .

$y = - 8 x - 20$

Step 2

Using the slope-intercept form, the slope is $- 8$ .

$m = - 8$
