Find the Slope 3x+20=-4y

$3 x + 20 = - 4 y$

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.

$y = m x + b$

Rewrite the equation as $- 4 y = 3 x + 20$ .

$- 4 y = 3 x + 20$

Divide each term in $- 4 y = 3 x + 20$ by $- 4$ and simplify.

Divide each term in $- 4 y = 3 x + 20$ by $- 4$ .

$\frac{- 4 y}{- 4} = \frac{3 x}{- 4} + \frac{20}{- 4}$

Simplify the left side.

Cancel the common factor of $- 4$ .

Cancel the common factor.

$\frac{- 4 y}{- 4} = \frac{3 x}{- 4} + \frac{20}{- 4}$

Divide $y$ by $1$ .

$y = \frac{3 x}{- 4} + \frac{20}{- 4}$

Simplify the right side.

Simplify each term.

Move the negative in front of the fraction.

$y = - \frac{3 x}{4} + \frac{20}{- 4}$

Divide $20$ by $- 4$ .

$y = - \frac{3 x}{4} - 5$

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

Reorder terms.

$y = - (\frac{3}{4} x) - 5$

Remove parentheses.

$y = - \frac{3}{4} x - 5$

Step 2

Using the slope-intercept form, the slope is $- \frac{3}{4}$ .

$m = - \frac{3}{4}$
