Transformations - Writing Rules

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)

Identify the transformation from ABC to A'B'C'.

• 90^o clockwise rotation

• 90^o counter clockwise rotation

• Reflection across the y-axis

• Reflection across the x-axis

The rule for rotation of 180 degrees is  
(x, y) --> _

• (-y, x)

• (-x, -y)

• (y, -x)

• (-y, -x)

Chose the correct transformation:
(x, y) ----- (-y, x)

• Reflection across x-axis

• Reflection across y-axis

• 90 degree clockwise rotation or 270 degree counter clockwise rotation

• 90 degree counter clockwise rotation or 270 degree clockwise rotation

The rule for reflection over the y-axis is  
(x, y) --> _

• (-x, y)

• (x, -y)

• (y, x)

• (-y, x)

Chose the correct transformation:
(x, y) ----- (-x, y)

• Reflection across x-axis

• Reflection across y-axis

• 90 degree clockwise rotation

• 90 degree counter clockwise rotation

Chose the correct transformation:
(x, y) ----- (-x, -y)

• 180 degree rotation

• 270 degree rotation

• 90 degree clockwise rotation

• 90 degree counter clockwise rotation
