Back

(x, y) --> (x + 2, y + 3)

Front

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

Back

Slides it

Front

What are the coordinates of a point after a reflection over the x-axis?

Back

(x, -y)

Front

Write the rule for the translation that moves a point 2 units to the right and 1 unit down.

Back

(x + 2, y - 1)

Front

If a triangle is reflected across the y-axis, what are the new coordinates of the point (2, 3)?

Back

(-2, 3)

Front

What is the effect of a reflection over the x-axis on the coordinates (a, b)?

Back

Front

What is the general rule for a translation of (h, k)?

Back

(x, y) --> (x + h, y + k)

Front

What is the difference between a translation and a reflection?

Back

A translation slides a figure, while a reflection flips it over a line.

Front

If a point (x, y) is translated 4 units left and 3 units up, what are the new coordinates?

Back

(x - 4, y + 3)
