What is a dilation in the context of coordinate geometry?

• A transformation that changes the position of a figure.

• A transformation that changes the size of a figure.

• A transformation that rotates a figure.

What should you remember about dilations and fractions?

• Multiplying by a fraction greater than 1 makes the figure smaller.

• Multiplying by a fraction less than 1 makes the figure bigger.

• Multiplying by a fraction less than 1 makes the figure smaller.

• Multiplying by a fraction greater than 1 makes the figure rotate.
