Find the Slope 7x-8y=-4

$7 x - 8 y = - 4$

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 $7 x$ from both sides of the equation.

$- 8 y = - 4 - 7 x$

Divide each term in $- 8 y = - 4 - 7 x$ by $- 8$ and simplify.

Divide each term in $- 8 y = - 4 - 7 x$ by $- 8$ .

$\frac{- 8 y}{- 8} = \frac{- 4}{- 8} + \frac{- 7 x}{- 8}$

Simplify the left side.

Cancel the common factor of $- 8$ .

Cancel the common factor.

$\frac{- 8 y}{- 8} = \frac{- 4}{- 8} + \frac{- 7 x}{- 8}$

Divide $y$ by $1$ .

$y = \frac{- 4}{- 8} + \frac{- 7 x}{- 8}$

Simplify the right side.

Simplify each term.

Cancel the common factor of $- 4$ and $- 8$ .

Factor $- 4$ out of $- 4$ .

$y = \frac{- 4 (1)}{- 8} + \frac{- 7 x}{- 8}$

Cancel the common factors.

Factor $- 4$ out of $- 8$ .

$y = \frac{- 4 \cdot 1}{- 4 \cdot 2} + \frac{- 7 x}{- 8}$

Cancel the common factor.

$y = \frac{- 4 \cdot 1}{- 4 \cdot 2} + \frac{- 7 x}{- 8}$

Rewrite the expression.

$y = \frac{1}{2} + \frac{- 7 x}{- 8}$

Dividing two negative values results in a positive value.

$y = \frac{1}{2} + \frac{7 x}{8}$

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

Reorder $\frac{1}{2}$ and $\frac{7 x}{8}$ .

$y = \frac{7 x}{8} + \frac{1}{2}$

Reorder terms.

$y = \frac{7}{8} x + \frac{1}{2}$

Step 2

Using the slope-intercept form, the slope is $\frac{7}{8}$ .

$m = \frac{7}{8}$
