Can someone please help me with these questions? I’m desperate! As always, I will give brainliest . I promise.

Since the centre of dilatation is the origin, we only require to multiply each of the coordinate points by the scale factor 3
(- 2, 1 ) → ( - 6, 3 )
(- 2, 3 ) → (- 6, 9 )
(1, 2 ) → (3, 6 )
(1, 3 ) → (3, 9 )
