Question: the point j(-5,5) is rotate 180 counterclockwise around the origin. what is the coordínate of the resulting point j?
Solution:
When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). Thus, we have that if the point j(-5,5) is rotated 180 counterclockwise around the origin then the resulting point j' is:
[tex]j^{\prime}(-(-5),-(5))\text{ = }j^{\prime}(5,-5)\text{ }[/tex]then, the correct answer is:
[tex]j^{\prime}(5,-5)\text{ }[/tex]
