What is the result of translating point M (-3, 5) using the rule (x, y) --> (x - 1, y)?

Back

M' = (-4, 5)

How do you translate triangle ABC to triangle A'B'C' if the translation rule is (x - 2, y + 9)?

Back

Apply the translation rule to each vertex of triangle ABC.

Front

If Point T is at (2, 4), where would Point T' be after translating 6 units up and 3 units to the right?

Back

T' = (5, 10)

What are the coordinates of point M' if M is at (-3, 5) and translated using (x, y) --> (x + 1, y)?

Back

M' = (-2, 5)

Front

What is the effect of translating a point 4 units left and 2 units down?

Back

Subtract 4 from the x-coordinate and 2 from the y-coordinate.
