Question

What will the coordinates of the image of point M be after it is rotated 90 degrees clockwise about the origin

Answer 1

The originals coodinates are (8,1). After a 90° rotation, we have to change the order of the coordinates and change the sig to the new y-coordinate like this

`(8,1)\rightarrow(1,8)\rightarrow(1,-8)`

so the new coordinates are (1,-8)
