Question

Rotate point x(5,8) 270 degrees counter clock wise what would the image point be?

Answer 1

The rule for 270 degrees counterclockwise is

`(x,y)\rightarrow(y,-x)`

In words, this rule means to transform the point, we just have to move or change the position of the coordinates and put the x-coordinate with opposite sign.

We use this rule to find the answer.

`(5,8)\rightarrow(8,-5)`

Therefore, the transformed point is (8,-5).
