Question

What is the image of (12,-8) after a dilation by a scale factor of 1/4 centered at the origin

Answer 1

(3, - 2 )

Explanation:

Since the dilatation is centred at the origin then multiply each of the original coordinates by the scale factor, that is

x - coordinate → 12 ×
`(1)/(4)` = 3

y- coordinate → - 8 ×
`(1)/(4)`

Thus

(12, - 8 ) → (3, - 2 )
