Find the Slope and y-intercept -x+4y=20

$- x + 4 y = 20$

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.

$y = m x + b$

Add $x$ to both sides of the equation.

$4 y = 20 + x$

Divide each term in $4 y = 20 + x$ by $4$ and simplify.

Divide each term in $4 y = 20 + x$ by $4$ .

$\frac{4 y}{4} = \frac{20}{4} + \frac{x}{4}$

Simplify the left side.

Cancel the common factor of $4$ .

Cancel the common factor.

$\frac{4 y}{4} = \frac{20}{4} + \frac{x}{4}$

Divide $y$ by $1$ .

$y = \frac{20}{4} + \frac{x}{4}$

Simplify the right side.

Divide $20$ by $4$ .

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

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

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

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

Reorder terms.

$y = \frac{1}{4} x + 5$

Step 2

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

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

$m = \frac{1}{4}$

$b = 5$

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

Slope: $\frac{1}{4}$

y-intercept: $(0, 5)$

Slope: $\frac{1}{4}$

y-intercept: $(0, 5)$
