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

$4 x + 5 y = 20$

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 $4 x$ from both sides of the equation.

$5 y = 20 - 4 x$

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

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

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

Simplify the left side.

Cancel the common factor of $5$ .

Cancel the common factor.

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

Divide $y$ by $1$ .

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

Simplify the right side.

Simplify each term.

Divide $20$ by $5$ .

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

Move the negative in front of the fraction.

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

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

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

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

Reorder terms.

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

Remove parentheses.

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