What is the image of (-9,0) after a dilation by a scale factor of 2 centered at
the origin?

Answer 1

The image is (-18,0)

Explanation:

Here, we want to find the image of the given point after dilation by the given scale factor

Mathematically, given a point with the pre-image (x,y) going under the dilation of scale factor k, centered at the origin, the coordinates of the image will be;

(kx , ky)

Applying this in the given scenario, we have

(2(-9) , 2(0))

= (-18,0)
