• 2 units to the left and 4 units up

• 2 units down and 4 units left

If the point (4, –1) is reflected in the x-axis, its new coordinates will be:

• (–4, 1)

• (–4, –1)

• (4, 1)

• (-1, 4)

Tick all the answers that describe the transformation of triangle B onto triangle A.

• Translation

• Rotation

• centre of rotation (-3, -2)

• 
• Reflection

Tick the two options that describe the rotation of shape B onto shape A.

• 90^o anti-clockwise

• 180^o

• centre of rotation (3, 3)

• centre of rotation (0, 0)

Reflect triangle A in the x-axis. Then, indicate the coordinates of point b in the image A'.

• (-4, 2)

• (4, -2)

• (2, 4)

• (-2, -4)

Rotate shape G 90º anti-clockwise about the origin. Then, indicate the coordinates of point b in the image G'.

• (-4, -3)

• (-3, -5)

• (-2, -3)

• (-3, -4)

Translate shape C by the vector $\left(\frac{-1}{5}\right)$ . Then, select the coordinates of point b in the image C'. 

(ignore the fraction line of the vector).
