Intro to Transformations and Translations

The point that is to be transformed is called the:

• Pre-Image
• Image
• Post-Image
• Transformation

After being transformed the new point is called a(n):

• Pre-Image
• Post Image
• Transformed
• Image

What does a translation do to a figure on the coordinate plane?

• Rotates it
• Flips it
• Shrinks it
• Slides it

Determine where X' would be if you translated X 3 units to the left and 9 units down.

• (-4, 4)
• (-10, 2)
• (-4, -5)
• (-1, 5)

Write a rule for the translation.

•  (x -1, y  + 2)
•  (x -2, y  + 1)
•  (x +2, y  - 1)
• (x +1, y  -  2)

In a translation, the preimage and image are ___________.

• congruent
• similar
• different
• red

When you translate, you ___________________ a number to x and y.

• Add or subtract

• Multiply or divide

• Add or multiply

• Subtract or divide

When translating left or right on a coordinate plane, what coordinate is affected?

• x-coordinate

• y-coordinate

When translating up or down on a coordinate plane, what coordinate is affected?

• x-coordinate

• y-coordinate

What is the algebraic notation of a figure is Translated 9 units right and 3 units down?

• (x, y) --> (x - 9, y + 3)
• (x, y) --> (x + 9, y - 3)
• (x, y) --> (x + 3, y - 9)
• (x, y) --> (9x, 3y)
