Rotate point A 90° counterclockwise around the origin to get point A'. Which of the following coordinate point would be A'? (-3, 2)

(3, -1)

(-2, 3)

(-3, -1)

(-2,3)

Step-by-step explanation:

the formula for a 90 degree counterclockwise rotation is, (x,y) ---> (-y,x)

so basically you switch x and y and then make your new x that was your y negative or opposite of was it was, so if it was positive it would be negative, and if it was negative, it would be positive. a 90 counterclockwise rotation is not the same as a clockwise 270-degree rotation.

Hope this helps! :)
