Rotation
$R_(O,270^(\circ))$ by
$270^(\circ)$ anti-clockwise about the origin has the rule:

$(x,y)\rightarrow (y,-x).$

Points M and N have coordinates (5,9) and (4,3), respectively.

Find the coordinates of ratation image points M' and N':

$M(5,9)\rightarrow M'(9,-5).$

$N(4,3)\rightarrow N'(3,-4).$

Answer: M'(9,-5), N'(3,-4)
