Find the Slope -4x-8y=0

$- 4 x - 8 y = 0$

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.

$y = m x + b$

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

$- 8 y = 4 x$

Divide each term in $- 8 y = 4 x$ by $- 8$ and simplify.

Divide each term in $- 8 y = 4 x$ by $- 8$ .

$\frac{- 8 y}{- 8} = \frac{4 x}{- 8}$

Simplify the left side.

Cancel the common factor of $- 8$ .

Cancel the common factor.

$\frac{- 8 y}{- 8} = \frac{4 x}{- 8}$

Divide $y$ by $1$ .

$y = \frac{4 x}{- 8}$

Simplify the right side.

Cancel the common factor of $4$ and $- 8$ .

Factor $4$ out of $4 x$ .

$y = \frac{4 (x)}{- 8}$

Cancel the common factors.

Factor $4$ out of $- 8$ .

$y = \frac{4 x}{4 \cdot - 2}$

Cancel the common factor.

$y = \frac{4 x}{4 \cdot - 2}$

Rewrite the expression.

$y = \frac{x}{- 2}$

Move the negative in front of the fraction.

$y = - \frac{x}{2}$

Write in $y = m x + b$ form.

Reorder terms.

$y = - (\frac{1}{2} x)$

Remove parentheses.

$y = - \frac{1}{2} x$

Step 2

Using the slope-intercept form, the slope is $- \frac{1}{2}$ .

$m = - \frac{1}{2}$
