Step 1:

\

The points are $\"\"$ .

\

Consider $\"\"$ .

\

Two point slope form is $\"\"$ .

\

Slope $\"\"$ .

\

Here, $\"\"$ .

\

Substitute $\"\"$ in slope.

\

$\"\"$ .

\

Substitute $\"\"$ in above equation.

\

$\"\"$

\

Hence, $\"\"$

\

Convert degree to radian, $\"\"$ .

\

$\"\"$ radians.

\

Solution:

\

The inclination $\"\"$ is $\"\"$ degrees.

\

The inclination $\"\"$ is $\"\"$ radians.
