Find the Slope 3x+2y=1

$3 x + 2 y = 1$

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.

$y = m x + b$

Subtract $3 x$ from both sides of the equation.

$2 y = 1 - 3 x$

Divide each term in $2 y = 1 - 3 x$ by $2$ and simplify.

Divide each term in $2 y = 1 - 3 x$ by $2$ .

$\frac{2 y}{2} = \frac{1}{2} + \frac{- 3 x}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 y}{2} = \frac{1}{2} + \frac{- 3 x}{2}$

Divide $y$ by $1$ .

$y = \frac{1}{2} + \frac{- 3 x}{2}$

Simplify the right side.

Move the negative in front of the fraction.

$y = \frac{1}{2} - \frac{3 x}{2}$

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

Reorder $\frac{1}{2}$ and $- \frac{3 x}{2}$ .

$y = - \frac{3 x}{2} + \frac{1}{2}$

Reorder terms.

$y = - (\frac{3}{2} x) + \frac{1}{2}$

Remove parentheses.

$y = - \frac{3}{2} x + \frac{1}{2}$

Step 2

Using the slope-intercept form, the slope is $- \frac{3}{2}$ .

$m = - \frac{3}{2}$
