Find the Slope of a Parallel Line y=-4x+9

$y = - 4 x + 9$

Use the slope-intercept form to find the slope.

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Using the slope-intercept form, the slope is $- 4$ .

$m = - 4$

$m = - 4$

All lines that are parallel to $y = - 4 x + 9$ have the same slope of $- 4$ .

$m_{parallel} = - 4$
