Triangle ABC

has vertices point A (1,4)
, point B (3, −2)
, and point C (−1, −2)
. Find the coordinates of A′, B′,
and C′
after a dilation with a scale factor of 3 and a center point of dilation at the origin.

Drag and drop the ordered pairs to the correct coordinates. Note: not all options will be used.

A′ (3,12)

B′ (9, −6)
C′ (−3, −6)
