Question

Find the slope of the line whose inclination is:
​(i) $0^{\circ }$

Answer 1

Given :
Inclination , $\theta =0^{\circ }$
We know that, the slope of a line is given by the $\tan$ of its indication .
$\therefore \text{slope}=\tan \theta$
$\Rightarrow \text{slope}=\tan 0^{\circ }$
$\Rightarrow \text{slope}=0$
Hence, the slope of the given line is $0$.
