Write in Slope-Intercept Form 5x+4y=20

$5 x + 4 y = 20$

Step 1

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Step 2

Rewrite in slope-intercept form.

Subtract $5 x$ from both sides of the equation.

$4 y = 20 - 5 x$

Divide each term in $4 y = 20 - 5 x$ by $4$ and simplify.

Divide each term in $4 y = 20 - 5 x$ by $4$ .

$\frac{4 y}{4} = \frac{20}{4} + \frac{- 5 x}{4}$

Simplify the left side.

Cancel the common factor of $4$ .

Cancel the common factor.

$\frac{4 y}{4} = \frac{20}{4} + \frac{- 5 x}{4}$

Divide $y$ by $1$ .

$y = \frac{20}{4} + \frac{- 5 x}{4}$

Simplify the right side.

Simplify each term.

Divide $20$ by $4$ .

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

Move the negative in front of the fraction.

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

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

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

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

Reorder terms.

$y = - (\frac{5}{4} x) + 5$

Remove parentheses.

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