Find the Slope and y-intercept 2x+3y=12

$2 x + 3 y = 12$

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 $2 x$ from both sides of the equation.

$3 y = 12 - 2 x$

Divide each term in $3 y = 12 - 2 x$ by $3$ and simplify.

Divide each term in $3 y = 12 - 2 x$ by $3$ .

$\frac{3 y}{3} = \frac{12}{3} + \frac{- 2 x}{3}$

Simplify the left side.

Cancel the common factor of $3$ .

Cancel the common factor.

$\frac{3 y}{3} = \frac{12}{3} + \frac{- 2 x}{3}$

Divide $y$ by $1$ .

$y = \frac{12}{3} + \frac{- 2 x}{3}$

Simplify the right side.

Simplify each term.

Divide $12$ by $3$ .

$y = 4 + \frac{- 2 x}{3}$

Move the negative in front of the fraction.

$y = 4 - \frac{2 x}{3}$

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

Reorder $4$ and $- \frac{2 x}{3}$ .

$y = - \frac{2 x}{3} + 4$

Reorder terms.

$y = - (\frac{2}{3} x) + 4$

Remove parentheses.

$y = - \frac{2}{3} x + 4$

Step 2

Use the slope-intercept form to find the slope and y-intercept.

Find the values of $m$ and $b$ using the form $y = m x + b$ .

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

$b = 4$

The slope of the line is the value of $m$ , and the y-intercept is the value of $b$ .

Slope: $- \frac{2}{3}$

y-intercept: $(0, 4)$

Slope: $- \frac{2}{3}$

y-intercept: $(0, 4)$
