Your answer must be listed as a coordinate so use parenthesis.

Answer 1

To rotate a point \( C(x, y) \) 270° clockwise around the origin, we can use the following transformation rule:

For a rotation of 270° clockwise, the new coordinates \( (x', y') \) can be calculated as:
\[
(x', y') = (y, -x)
\]

Given \( C(10, 3) \), we can apply the transformation:

1. \( x = 10 \)
2. \( y = 3 \)

Now we will substitute these values into the transformation:

\[
x' = 3
\]
\[
y' = -10
\]

Thus, the coordinates of point \( C' \) after the rotation are:

\[
C'(3, -10)
\]

So, the answer is \( (3, -10) \).
