$θ = \frac{5 π}{6}$

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

$y = m x + b$

Find the values of $m$ and $b$ using the form $y = m x + b$ . Since there is no $y$ and $x$ is linear, $θ = \frac{5 π}{6}$ is a vertical line. Vertical lines have no y-intercept and undefined slope.
