Question

Find the slope of the line whose inclination is ${45}^o$.

Answer 1

We know that if $\theta$ is the inclination of a straight line, then $\tan \theta$ is called the slope (or gradient) of a line. The slope of a line is usually denoted by $m$.

Here, it is given that $\theta ={45}^0$, therefore, the slope of the line is:

$m=\tan {45}^0=1$

Hence, the slope of the line is $1$.
