Step 1 :

The slope-intercept form of a line equation is $\"\"$ .

Inclination and slope :

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

$\"\"$

Step 2 :

The equation of a line is $\"\"$ .

Rewrite the expression :

$\"\"$

Compare the line equation $\"\"$ with $\"\"$ .

The slope is $\"\"$ , then the inclination is

$\"\"$

Conversion from radians to degrees :

$\"\"$

The angle of inclination is $\"\"$ radians or $\"\"$ .

Solution :

The angle of inclination is $\"\"$ radians or $\"\"$ .
