$(3,-1)" and "(-2,-8)$

$"assuming rotation is about the origin"$

$"under a clockwise rotation about the origin of "pi/2$

$• " a point "(x,y)to(y,-x)$

$(1,3)to(3,-1)" and "(8,-2)to(-2,-8)$

A line segment with endpoints at (1, 3)(1, 3) and (8, -2)(8, -2) is rotated clockwise by pi/2pi/2. What are the new endpoints of the line segment?
