Question

The slope of the line with inclination ${45}^o$ is:

• A. $1$
• B. $\frac{1}{2}$
• C. $\frac{\sqrt{3}}{2}$
• D. $0$

Answer 1

Answer: (A)

$1$

Slope of a line with inclination $\theta$ is given by $\tan \theta$
Here, $\theta ={45}^{\circ }$

$\therefore$ Slope of the line with inclination ${45}^{\circ }$
$\tan {45}^{\circ }=1$

Hence, option A is correct.
