Question

Rotate the object 270° counter clock wisePoint A: (-3,1)Point B: (1,3)Point C: (-3,5)

Answer 1

To rotate something 270° is to change the order in the coodinates, and after that change the sign in the new y-coordinate. For example:

$(-3,1)\rightarrow(1,-3)\rightarrow(1,3)$

so the answer for the point A is (1,3)

For the point B is (3,-1)

For the point C is (5,3)
