2 x + 3 y = 6

$2 x + 3 y = 6$

Step 1

Rewrite in slope-intercept form.

Step 1.1

The slope-intercept form is

y = m x + b

$y = m x + b$ , where

m

$m$ is the slope and

b

$b$ is the y-intercept.

y = m x + b

$y = m x + b$

Step 1.2

Subtract

2 x

$2 x$ from both sides of the equation.

3 y = 6 - 2 x

$3 y = 6 - 2 x$

Step 1.3

Divide each term in

3 y = 6 - 2 x

$3 y = 6 - 2 x$ by

3

$3$ and simplify.

Step 1.3.1

Divide each term in

3 y = 6 - 2 x

$3 y = 6 - 2 x$ by

3

$3$ .

\frac{3 y}{3} = \frac{6}{3} + \frac{- 2 x}{3}

$\frac{3 y}{3} = \frac{6}{3} + \frac{- 2 x}{3}$

Step 1.3.2.1.1

Cancel the common factor.

\frac{3 y}{3} = \frac{6}{3} + \frac{- 2 x}{3}

$\frac{3 y}{3} = \frac{6}{3} + \frac{- 2 x}{3}$

Step 1.3.2.1.2

Divide

y

$y$ by

1

$1$ .

y = \frac{6}{3} + \frac{- 2 x}{3}

$y = \frac{6}{3} + \frac{- 2 x}{3}$

y = \frac{6}{3} + \frac{- 2 x}{3}

$y = \frac{6}{3} + \frac{- 2 x}{3}$

y = \frac{6}{3} + \frac{- 2 x}{3}

$y = \frac{6}{3} + \frac{- 2 x}{3}$

Step 1.3.3.1.1

Divide

6

$6$ by

3

$3$ .

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

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

Step 1.3.3.1.2

Move the negative in front of the fraction.

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

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

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

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

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

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

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

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

Step 1.4

Write in

y = m x + b

$y = m x + b$ form.

Step 1.4.1

Reorder

2

$2$ and

- \frac{2 x}{3}

$- \frac{2 x}{3}$ .

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

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

Step 1.4.2

Reorder terms.

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

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

Step 1.4.3

Remove parentheses.

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

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

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

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

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

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

Step 2

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

Step 2.1

Find the values of

m

$m$ and

b

$b$ using the form

y = m x + b

$y = m x + b$ .

m = - \frac{2}{3}

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

b = 2

$b = 2$

Step 2.2

The slope of the line is the value of

m

$m$ , and the y-intercept is the value of

b

$b$ .

Slope:

- \frac{2}{3}

$- \frac{2}{3}$

y-intercept:

(0, 2)

$(0, 2)$

Slope:

- \frac{2}{3}

$- \frac{2}{3}$

y-intercept:
