Triangle PQR is translated 5 units left and 2 units up. Write a rule that describes this transformation.
Move the correct answer to each box. Not all answers will be used.
The rule used for the translation is: (x, y) --> (x - 5, y + 2)
-5, 2
whats the rule you used

Question
A figure is graphed on a coordinate grid as shown.
The figure is rotated 270° clockwise with the origin as the center of rotation to create a new figure. Which rule describes this transformation?
Responses
A (x, y) → (-y, x)( x, y ) → (- y , x )
B (x, y) → (-y, -x)( x, y ) → (- y , - x )
C (x, y) → (x + 1, y - 2)( x, y ) → ( x + 1, y - 2)
D (x, y) → (x - 2, y + 1)
