Figure ABCD is a rhombus with point A (3, −1). What rule would rotate the figure 270° counterclockwise? (6 points)

(x,y)→(−y,x)
(x,y)→(y,x)
(x,y)→(y,−x)
(x,y)→(−y,−x)

These are rules that you just have to memorize until you finish the class and t hen you can forget it all haha If you go to this website, you'll find the rule https://calcworkshop.com/transformations/rotation-rules/#:~:text=When%20rotating%20a%20point%20270,y%20and%20make%20x%20negative. Alternatively, if you'd like to figure it out from the numbers and try to see whether x or y gets switched and one of them becomes negative, you can use this image to do that
