Single Transformations

Which transformation is described by the rule:
   $\left(x,y\right)\ \rightarrow\ \left(x,\ -y\right)$  

• reflection across the x-axis

• reflection across the y -axis

• rotation  $90\degree$  counter-clockwise about the origin

• rotation  $90\degree$  clockwise about the origin

• rotation  $180\degree$  about the origin

Which transformation is described by the rule:
 $\left(x,\ y\right)\rightarrow\left(x-3,\ y\right)$  

• translate right 3

• translate left 3

• translate up 3

• translate down 3

Which transformation is described by the rule:
(x, y) -------> (x, y - 2) is a translation of 2 units up.  $\left(x,\ y\right)\rightarrow\left(x,\ y+2\right)$  

• translation 2 up

• translation 2 down

• translation 2 left

• translation 2 right
