Find the Slope and y-intercept 3x-4y=4

$3 x - 4 y = 4$

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 $3 x$ from both sides of the equation.

$- 4 y = 4 - 3 x$

Divide each term in $- 4 y = 4 - 3 x$ by $- 4$ and simplify.

Divide each term in $- 4 y = 4 - 3 x$ by $- 4$ .

$\frac{- 4 y}{- 4} = \frac{4}{- 4} + \frac{- 3 x}{- 4}$

Simplify the left side.

Cancel the common factor of $- 4$ .

Cancel the common factor.

$\frac{- 4 y}{- 4} = \frac{4}{- 4} + \frac{- 3 x}{- 4}$

Divide $y$ by $1$ .

$y = \frac{4}{- 4} + \frac{- 3 x}{- 4}$

Simplify the right side.

Simplify each term.

Divide $4$ by $- 4$ .

$y = - 1 + \frac{- 3 x}{- 4}$

Dividing two negative values results in a positive value.

$y = - 1 + \frac{3 x}{4}$

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

Reorder $- 1$ and $\frac{3 x}{4}$ .

$y = \frac{3 x}{4} - 1$

Reorder terms.

$y = \frac{3}{4} x - 1$

Step 2

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

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

$m = \frac{3}{4}$

$b = - 1$

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

Slope: $\frac{3}{4}$

y-intercept: $(0, - 1)$

Slope: $\frac{3}{4}$

y-intercept: $(0, - 1)$
