You can do this by many method.
One is by Slope $= \left(\text{rise")/("run}\right)$

Here you can find the slope by drawing a triangle with hypotenuse as the line.

The next method is by

$\text{Slope} = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

where you can take any two coordinates from the line.

For e.g.

$\left({x}_{1} , {y}_{1}\right) = \left(1 , 2\right)$

$\left({x}_{2} , {y}_{2}\right) = \left(4 , 3\right)$

$\text{Slope} = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}} = \frac{3 - 2}{4 - 1} = \frac{1}{3}$

The next method is by

$\text{slope} = \tan Q$

where $Q$ is the angle between the line and X-axis.
