What is Rotation ?

A rotation is a type of transformation which takes each point in a figure and rotates it a certain number of degrees around a given point.

As we know , the rule for rotation of $R_{90}$ is given by :-

(x,y)⇒(-y,x)

In the above formula  (x,y) is the point of pre-image and (-y,x) is a point of image.

Since ,given point of pre-image : A(8,2)

After the rotation of  $R_{90}$,  the image point are :-

(8,2) ⇒ (-2,8)

Therefore,

The image point of A(8,2) is (-2,8) .
