Question

Question 3 The point W(-13,9) was transformed to W'(-9, -13) by a rotation around the origin. Which of the following best describes this rotation? Answer 90° counterclockwise 270° counterclockwise 90° clockwise

Answer 1

The initial position of the point W (-13, 9)

The transformed position of the point W' (-9, -13)

when transformed 90 degrees counterclockwise, the coordinates of the original position is swapped and the y-coordinate is negated

That is if the W coordinate is (x,y), the transformation W coordinate in 90 degrees counter-clockwise will be (-y, -x )

Since W is (-13, 9)

Then W' will be ( -9 , -13)...In 90 degrees counterclockwise
