Find the Slope of a Parallel Line y=8-9x

$y = 8 - 9 x$

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.

$y = m x + b$

Reorder $8$ and $- 9 x$ .

$y = - 9 x + 8$

Using the slope-intercept form, the slope is $- 9$ .

$m = - 9$

All lines that are parallel to $y = - 9 x + 8$ have the same slope of $- 9$ .

$m_{parallel} = - 9$
