What transformation is represented by the rule (x, y) --> (x + 2, y - 3)?

Back

Slide right 2, down 3.

Front

Write the algebraic rule for translating a figure 9 units right and 3 units down.

Back

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

Front

What is the algebraic notation for a translation that moves a point 2 units left and 1 unit up?

Back

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

Front

What transformation produces a similar figure?

Back

Dilation.

Front

What is the rule for reflection over the y-axis?

Back

(x, y) --> (-x, y)

Front

What does a translation do to a figure?

Back

Moves the figure without changing its shape or size.

Front

If a figure is reflected over the x-axis, what is the algebraic notation?

Back

(x, y) --> (x, -y)

Front

What is the effect of a dilation with a scale factor greater than 1?

Back

The figure enlarges.
