7: The point B (-8,5) is dilated from the origin with a scale factor of 12 . What are the coordinates of B'? A (−6,3) B (−4,2.5) C (−16,10) D (−10,7)

The correct option is option B.

The coordinate of B' is (-4,2.5).

Step-by-step explanation:

Formula of dilation:

Image = (pre-image)×(scale factor)

Scale factor:

The amount by which the shrinks or grows is called " scale factor".

Given point is B(-8,5)

Scale factor is .

The co-ordinate of image B is

                                                 =(-4,2.5)

The coordinate of B' is (-4,2.5).
