Station 6 (Transformation)

Determine how to translate triangle ABC to triangle A'B'C'.

• (x-2, y+5)
• (x+2, y-9)
• (x-2, y+9)
• (x-9, y+2)

What transformation is happening?
(x, y) ----> (x + 2, y - 3) 

• slide up 2, left 3
• slide right 2, up 3
• slide right 2, down 3
• slide left 3, right 2

Reflect the point (2, -4) over the y-axis.

• (-4, 2)
• (-2, 4)
• (-2, -4)
• (2, 4)

Describe the transformation:

(x, y) -> (x-2, y+7)

• Translation 2 units to the left & 7 units up

• Translation 2 units to the left & 7 units down

• Translation 2 units to the right & 7 units up

• Translation 2 units to the right & 7 units down

What sequence of transformations will map trapezoid A to its image A'?

• Reflection across vertical line, then translation downwards

• Rotation 180 degrees, then reflection over x-axis

• Reflection across x-axis, then translation upwards

• Rotation 180 degrees, then reflection over y-axis

The ordered pair (-3, 4) is reflected across the x-axis. What is the new ordered pair?

• (-3, -4)
