Find the Slope and y-intercept 7x-y=4

$7 x - y = 4$

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.

$- y = 4 - 7 x$

Divide each term in $- y = 4 - 7 x$ by $- 1$ and simplify.

Divide each term in $- y = 4 - 7 x$ by $- 1$ .

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

Simplify the left side.

Dividing two negative values results in a positive value.

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

Divide $y$ by $1$ .

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

Simplify the right side.

Simplify each term.

Divide $4$ by $- 1$ .

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

Move the negative one from the denominator of $\frac{- 7 x}{- 1}$ .

$y = - 4 - 1 \cdot (- 7 x)$

Rewrite $- 1 \cdot (- 7 x)$ as $- (- 7 x)$ .

$y = - 4 - (- 7 x)$

Multiply $- 7$ by $- 1$ .

$y = - 4 + 7 x$

Reorder $- 4$ and $7 x$ .

$y = 7 x - 4$

Step 2

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

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

$m = 7$

$b = - 4$

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

Slope: $7$

y-intercept: $(0, - 4)$

Slope: $7$

y-intercept: $(0, - 4)$
