Find the Slope and y-intercept 2x+4y=4

$2 x + 4 y = 4$

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.

$4 y = 4 - 2 x$

Divide each term in $4 y = 4 - 2 x$ by $4$ and simplify.

Divide each term in $4 y = 4 - 2 x$ by $4$ .

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

Simplify the left side.

Cancel the common factor of $4$ .

Cancel the common factor.

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

Divide $y$ by $1$ .

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

Simplify the right side.

Simplify each term.

Divide $4$ by $4$ .

$y = 1 + \frac{- 2 x}{4}$

Cancel the common factor of $- 2$ and $4$ .

Factor $2$ out of $- 2 x$ .

$y = 1 + \frac{2 (- x)}{4}$

Cancel the common factors.

Factor $2$ out of $4$ .

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

Cancel the common factor.

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

Rewrite the expression.

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

Move the negative in front of the fraction.

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

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

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

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

Reorder terms.

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

Remove parentheses.

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

Step 2

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

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

$m = - \frac{1}{2}$

$b = 1$

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

Slope: $- \frac{1}{2}$

y-intercept: $(0, 1)$

Slope: $- \frac{1}{2}$

y-intercept: $(0, 1)$
