Question

Demonstrating the properties of rotations, if a line segment with endpoints (0,−3)
and (0,−7)
is rotated 90°
clockwise, what is an endpoint of this rotated segment?(1 point)

(0, 7)

left parenthesis 0 comma 7 right parenthesis

(3, 0)

left parenthesis 3 comma 0 right parenthesis

(−3, 0)

left parenthesis negative 3 comma 0 right parenthesis

(0, 3)

Answer 1

Rotation 90° clockwise sends (x,y) to (y,−x).
(0,−3) → (−3,0) and (0,−7) → (−7,0).

So an endpoint is (−3, 0).
