Transformations

Identify the transformation from B to D.

• 90^o Clockwise Rotation
• 180^o Rotation
• 270^o clockwise Rotation
• 360^o Rotation

What transformation is happening?
(x, y) ----> (x + 2, y - 3) 

• slide up 2, left 3
• slide right 2, up 3
• slide right 2, down 3
• slide left 3, right 2

If (3,5)--->(7,10)  then the rule for the translation is:

• (x+4,y-5)
• (x+4,y+5)
• (x-4,y+5)
• 
  (x,y)
