Which rule would dilate shows a scale factor of 4

• (x, y) → (y, x)

• (x, y) → (x + 4, y + 4)

• (x, y) → (x, -y)

• (x, y) → (4x, 4y)

Match the following dilations by a scale factor of 1/2.

• (5,1)

• (0,0)

• (0,0)

• (6,8)

• (-3, -4)

• (10,2)

• (0, -5)

• (-6,-8)

• (3,4)

• (0, -10)

Answer explanation

Note that 0/2 is still 0

so (0,0) dilated by 1/2 is still at (0,0)

(0,-10) dilated by a 1/2 is at

(0, -5)
