Translations and Reflections

Describe the transformation: (x, y) --> (x + 2, y - 3) 

• Translation:

  slide 2 up, 3 left

• Reflection:

  slide 2 right, 3 up

• Translation: slide 2 right, 3 down

• Reflection:

  slide 3 left, 2 down

The transformation that moves a shape like a slide is called a ______________.

• translation

• reflection

• rotation

• transformation

What is the arrow notation for shape that is translated 6 units right and 5 units up?

• (x, y) --> (x - 6, y + 5)

• (x, y) --> (x + 6, y + 5)

• (x, y) --> (x + 5, y - 6)

• (x, y) --> (x + 5, y + 6)

The _____________ is the original shape before a transformation takes place.

• pre-image

• image

A triangle is drawn on the coordinate plane. It is translated 4 units right and 3 units down. Which arrow notation rule correctly describes the translation?

• (x, y) → (x + 3, y – 4)

• (x, y) → (x + 3, y + 4)

• (x, y) → (x + 4, y – 3)

• (x, y) → (x + 4, y + 3)

What is the arrow notation for a shape that is translated 8 units left and 2 units up?

• (x, y) --> (x - 8, y + 2)

• (x, y) --> (x + 8, y - 2)

• (x, y) --> (x + 2, y - 8)

• (x, y) --> (x + 2, y - 8)

The solid-lined shape is the pre-image and the dashed-lined shape is the image.  What is the algebraic representation (rule) for this translation?

• (x, y) --> (x - 7, y + 4)

• (x, y) --> (x + 7, y - 4)

• (x, y) --> (x + 4, y - 7)

• (x, y) --> (x - 4, y + 7)

The solid-lined shape is the pre-image and the dashed-lined shape is the image.  What is the algebraic representation (rule) for this translation?

• (x, y) --> (x - 6, y + 8)

• (x, y) --> (x + 6, y - 8)

• (x, y) --> (x + 8, y + 6)

• (x, y) --> (x - 8, y - 6)

The solid-lined shape is the pre-image and the dashed-lined shape is the image.  What is the algebraic representation (rule) for this translation?

• (x, y) --> (x - 5, y + 4)

• (x, y) --> (x + 5, y - 4)

• (x, y) --> (x + 4, y + 5)

• (x, y) --> (x - 4, y - 5)

What is the algebraic representation (rule) for this translation?

•  (x , y) --> (x - 1, y  + 3)

•   (x , y) --> (x + 3, y  + 1)

•  (x , y) --> (x + 2, y  - 1)

•  (x , y) --> (x + 1, y  -  3)
