Question

Find the slope of a line whose inclination with the positive direction of $x$ axis is $0^{\circ }$

• A. $2$
• B. $1$
• C. $0$
• D. $1.5$

Answer 1

Answer: (C)

$0$

The slope of the line whose inclination with the positive direction of x axis$=0^o$
So as we represent the angle with the positive direction of x-axis as slope and we represent with the help of $\tan \theta .$

Here, in this case $\tan \theta =0$

$\theta ={\tan }^{-1}0\theta =0^o\tan \theta =m\Rightarrow m=0$
