$3 x + 4 y = - 5$

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 2.2.3.1.1

Move the negative in front of the fraction.

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

Step 2.2.3.1.2

Move the negative in front of the fraction.

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

Step 2.3.1

Reorder $- \frac{5}{4}$ and $- \frac{3 x}{4}$ .

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

Step 2.3.2

Reorder terms.

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

Step 2.3.3

Remove parentheses.

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