how to write the rule for the rotation of #14

It is required to write the rule for the given rotation.
To do this, take a point in the pre-image and image, and then form a rule.
Notice that the points are H(-4,4) and H'(4,-4).
Notice that both coordinates are negated.
Hence, the rule is:
[tex](x,y)\rightarrow(-x,-y)[/tex]
