DILATIONS

What is the rule for the dilation pictured below?

• (x, y) → (½x, ½y)
• (x, y) → (x + 2, y + 2)
• (x, y) → (x + 2, y + 2)
• (x, y) → (2x, 3y)

The point that is to be dilated is called the:

• Pre-Image

• Image

• Post-Image

• Transformation

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

• Pre-Image

• Post Image

• Transformed

• Image

How do you write the algebraic notation when the scale factor is 3?

• (x, y) goes to (1/3x, 1/3y)
• (x, y) goes to (-3x, -3y)
• (x, y) goes to (x + 3, y + 3)
• (x, y) goes to (3x, 3y)

How do you write the algebraic notation when the scale factor is 1/2?

• (x, y) goes to (2x, 2y)
• (x, y) goes to (1/2x, 1/2y)
• (x, y) goes to (-2x, -2y)
• (x, y) goes to (2x, 1/2y)
