What is the point notation of a figure that is translated 9 units right and 3 units down?

• (x, y) --> (x - 9, y + 3)

• (x, y) --> (x + 9, y - 3)

• (x, y) --> (x + 3, y - 9)

• (x, y) --> (9x, 3y)

The dashed figure is the image of the solid figure. What is the point notation for the translation?

• (x, y) --> (x - 7, y + 4)

• (x, y) --> (x + 7, y - 4)

• (x, y) --> (x + 4, y - 7)

• (x, y) --> (7x, 4y)

Rotation Rules (clockwise):
