Rotate the point (9, 5) on a geometric figure 270 degrees clockwise. What is the new point? (1 point)

О (-5,-9)
0 (-5,9)
0 (-9,-5)
0 (5, 9)

1 answer

To rotate a point \((x, y)\) 270 degrees clockwise, we can use the following rule:

  • The new coordinates after a 270-degree clockwise rotation will be \((y, -x)\).

Given the point \((9, 5)\):

  1. \(x = 9\)
  2. \(y = 5\)

Applying the rule:

\[ \text{New point} = (y, -x) = (5, -9) \]

So, the new point after the 270-degree clockwise rotation is \((5, -9)\).

It seems I made a mistake in identifying your options. However, it looks like the points provided in the choices do not include \((5, -9)\).

None of the options you provided are correct based on the calculation.

To clarify:

  • The correct new point when rotating \((9, 5)\) by 270 degrees clockwise is \((5, -9)\).
