$- 1 = - 2 x + y$

Step 1

Rewrite in slope-intercept form.

Step 1.1

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 1.2

Rewrite the equation as $- 2 x + y = - 1$ .

$- 2 x + y = - 1$

Step 1.3

Add $2 x$ to both sides of the equation.

$y = - 1 + 2 x$

Step 1.4

Reorder $- 1$ and $2 x$ .

$y = 2 x - 1$

Step 2

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

Step 2.1

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

$m = 2$

$b = - 1$

Step 2.2

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

Slope: $2$

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

Slope: $2$

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