A. (x,y) - (y,-x) is the rule to rotate the figure 90 degrees clockwise.

Answer:

A. [tex](x,y)\rightarrow (y,-x)[/tex]

Step-by-step explanation:

We have been given that figure ABCD is a rectangle with point A (−2, 5). We are asked to choose the rule that would rotate the figure 90° clockwise.

We know that rule of rotating a figure 90 degrees clockwise is: [tex](x,y)\rightarrow (y,-x)[/tex]

Upon looking at our given choices we can see that option A is the correct choice.

After rotating our given point 90 degree clockwise, the coordinates of point A would be:

[tex](-2,5)\rightarrow (5,--2)=(5,2)[/tex]
