Question

If the point A at (5, 3) is rotated clockwise about the origin through 90°, whatwill be the coordinates of the new point?O (5,-3)O (3,-5)O (-3,-5)O (3,5)

Answer 1

The rotation of a point 90° clockwise about the origin is given as,

$(x,y)\rightarrow(y,-x)$

The rotation of point A at (5, 3) in the clockwise direction about the origin through 90° will be,

$(5,3)\rightarrow(3,-5)$

Hence, option 2 is the correct answer.
