Find the Inclination $\theta$ (In Radians and Degrees)of the Line Passing Through the Points

Find the inclination $\theta$ (in radians and degrees) of the line passing through the points.Round your answer to four decimal places for radians and round your answer to one decimal places for degree.​ $( 12,9 ) , ( 4,3 )$ ​

A) $\Theta \approx 0.6435 \text { radians } \approx 36.9$
B) $\Theta \approx 0.6435 \text { radians } \approx 37.9$
C) $\Theta \approx 0.6435 \text { radians } \approx 35.9$
D) $\Theta \approx 0.6435 \text { radians } \approx 38.9$
E) $\Theta \approx 0.6435 \text { radians } \approx 34.9$
