$y = 4$

Use the slope-intercept form to find the slope.

Tap for more steps...

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 $0$ .

$m = 0$

All lines that are parallel to $y = 4$ have the same slope of $0$ .

$m_{parallel} = 0$
