Answer :

The rule for 270 degrees counterclockwise is

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

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.

[tex](5,8)\rightarrow(8,-5)[/tex]

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