Use one or more transformations to transform the pre-image (purple) onto the image (white). Translate Rotate
* Reflect

(You cant tpuch the grey lines )

 This is a translation of 12 units to the right.

translation written (x,y) -> (x+12,y+0)

Step-by-step explanation:

Pick a point on the pre-image, and count how many squares it has to move to end up at the corresponding point in the image.

Add that value to the coordinate x  for horizontal movement, here +12.

Add to the coordinate y for vertical movement. here 0.
