The image of the point (-4, 3) under a rotation of 90° (counterclockwise) centered at the origin is ______. Answer in (x, y) format.
Question
Solution 1
To find the image of a point under a rotation of 90° counterclockwise about the origin, we can use the rotation matrix for 90° counterclockwise rotation. The rotation matrix is:
[0 -1] [1 0]
We multiply this matrix by the point (-4, 3) to get the new coordinates.
So,
0*(-4) - 13 = -3 1(-4) + Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
