# A line segment with endpoints at (1 , -2 ) and (6, -7 ) is rotated clockwise by pi/2. What are the new endpoints of the line segment?

Feb 22, 2018

New coordinates of the end points are

A’((-2),(-1)) and B’((-7),(-6))

#### Explanation:

$A \left(1 , - 2\right) , B \left(6 , - 7\right)$. Rotted clockwise by $\frac{\pi}{2}$

A((1),(-2)) => A’((-2),(-1)) IV to III quadrant.

B((6),(-7)) => B’((-7),(-6)) IV to III quadrant.
