Show Answer

Answer:

Correct Answer: D

Solution:

Midpoint of the line joining the point $ (4,-5) $ and $ (-2,9) $ is $ ( \frac{4-2}{2},\frac{-5+9}{2} ) $ i.e. (1, 2). \Inclination of straight line passing through point (-3, 6) and midpoint $ (1,2) $ is $ m=\frac{2-6}{1+3}=\frac{-4}{4}=-1=\tan \theta $ . Þ $ \theta =\frac{3\pi }{4} $ .
