Find the Slope -y=9

$- y = 9$

Step 1

Rewrite in slope-intercept form.

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

$y = m x + b$

Divide each term in $- y = 9$ by $- 1$ and simplify.

Divide each term in $- y = 9$ by $- 1$ .

$\frac{- y}{- 1} = \frac{9}{- 1}$

Simplify the left side.

Dividing two negative values results in a positive value.

$\frac{y}{1} = \frac{9}{- 1}$

Divide $y$ by $1$ .

$y = \frac{9}{- 1}$

Simplify the right side.

Divide $9$ by $- 1$ .

$y = - 9$

Step 2

Using the slope-intercept form, the slope is $0$ .

$m = 0$
