Step 1 :

Inclination and slope :

If a non vertical line has inclination $\"\"$ and slope m, then

$\"\"$

Step 2 :

The inclination angle $\"\"$ radians.

The slope is $\"\"$ .

Substitute $\"\"$ in above equation.

$\"\"$

The slope of the line is $\"\"$

Solution :

The slope of the line is $\"\"$
