Question

What is the image of the point (-7,9) after a rotation of 270 counterclockwise about the origin

Answer 1

Answer is (9, 7)

Step by step

Rule: 270 degrees counterclockwise about the origin our point A(x,y) becomes A'(y,-x).

This means, we switch x and y and make x negative.

So

(-7, 9) ➡️ ( 9, 7)
