Given a point on a geometric figure (1, 2) , what is the new point when the point is rotated clockwise about the origin 90 degrees?(1 point)

1 answer

To rotate a point \((x, y)\) clockwise about the origin by 90 degrees, you can use the following transformation:

\[ (x, y) \rightarrow (y, -x) \]

For the point \((1, 2)\):

  • \(x = 1\)
  • \(y = 2\)

Applying the transformation gives:

\[ (1, 2) \rightarrow (2, -1) \]

Thus, the new point after rotating \((1, 2)\) 90 degrees clockwise about the origin is \((2, -1)\).
