Transformation Algebraic Rules

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

• Reflection over the y-axis

• Reflection over the x-axis

• Translation 

• Rotation 180 ° 

Chose the correct transformation:
(x, y) --> (x , y + 2)

• Translation 2 units up

• Translation 2 units left

• Translation 2 units down

• Translation 2 units right

Which rule describes the action of the coordinates when a figure is dilated by a scale factor of 2?

• (x, y)→(x+2, y+2)

• (x, y)→(2x, 2y)

• (x, y)→(x/2, y/2)

• (x, y)→(x-2, y-2)

Which rule would result in a translation of 2 units left and 3 units up?

• (x, y) → (2x, 3y)

• (x, y) → (x - 2, y + 3)

• (x, y) → (-x, -y)

• (x, y) → (x + 2, y - 3)
