$θ = \frac{π}{3}$

Step 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 2

Find the values of $m$ and $b$ using the form $y = m x + b$ . Since there is no $y$ and $x$ is linear, $θ = \frac{π}{3}$ is a vertical line. Vertical lines have no y-intercept and undefined slope.

Vertical line at $x = \frac{π}{3}$
