Question

Find the inclination of the line whose slope is:​
(i) $0$

Answer 1

Given :
slope $=0$
We know , if $\tan \theta$ is the slope of line; then the inclination of the line is $\theta$
$\Rightarrow \tan \theta =0$
$\Rightarrow \tan \theta =\tan 0^{\circ }$ [From the trigonometric table]
$\Rightarrow \theta =0^{\circ }$

Hence, the inclination of the line is $0^{\circ }$.
