Dilations

A dilation is which of the following: 

• An enlargement
• A reduction
• Either an enlargement or a reduction
• Neither an enlargement or a reduction

If the scale factor is less than one, the new figure will be

• an enlargement
• a reduction
• a scale factor
• bigger

If the scale factor is greater than one, the new figure will be

• a reduction
• an enlargement
• a scale
• not proportional

• (12,0)
• (12,12)

Which of the following is the algebraic representation for a dilation?

• (x, y) → (x, 3y)
• (x, y) → (3x, 3y)
• (x, y) → (x, y - 3)
• (x, y) → (.5x, .4y)

• enlargement

• reduction (shrink)
