# Find the Slope of the Lines Which Make the Following Angle with the Positive Direction of X-axis: 2 π 3 - Mathematics

Find the slope of the lines which make the following angle with the positive direction of x-axis:

$\frac{2\pi}{3}$

#### Solution

$\theta = \frac{2\pi}{3}$

$\therefore \text { Slope of the line } = m = \tan\theta$

$\Rightarrow \text { Slope of the line }= \tan\left( \frac{2\pi}{3} \right) = - \tan\left( \frac{\pi}{3} \right) = - \sqrt{3}$

Hence, the slope of the line is $- \sqrt{3}$.

Is there an error in this question or solution?
