`(1/4, 3/2), (1/3, 1/2)` Find the inclination 'theta' (in radians and degrees) of the line with slope m.

Given `(1/4,3/2), (1/3, 1/2)`

Find the slope of the line passing through the two points using the formula

`m=(y_2-y_1)/(x_2-x_1)`

`m=(1/2-3/2)/(1/3-1/4)` =-12

The slope of the line is -12.

Find the inclination.

`theta=arctan(-12)=94.8^@=1.6539` radians.

The inclination is 94.8 degrees or 1.6539 radians.
