we have

(x,y). rotation through 90° anti-

clockwise about the origin(-y,x)

  • I.(-4,-8)

Step-by-step explanation:

In the given point(-8,4)

we have to rotate it up to 90° in anti clockwise about its origin

so,

(x,y)=(-y,x)

Hence,

The new position of the point (−8, 4) when rotated through 90° anti-clockwise about the origin is (-4,-8)
