# Find the inclination of the line whose slope is 1?

$(a)\;45^{\large\circ}\qquad(b)\;60^{\large\circ}\qquad(c)\;55^{\large\circ}\qquad(d)\;35^{\large\circ}$

Can you answer this question?

Let $\alpha$ be the inclination of a line then its slope will be $\tan \alpha$
$\tan \alpha =1$
$\alpha =45^{\large\circ}$
Hence (a) is the correct option.
