Question

What is the image of the point (-3 , 14) after a counterclockwise rotation about the origin through an angle of 90 degrees?

Answer 1

So the value of 14 is now negative 14. Notice that if the original -coordinate was already negative, then it would change to be a positive value. And that's the answer for the image of the point negative three, 14 after a rotation of 90 degrees about the origin. It's the coordinates negative 14, negative three.
