    Answer:

    The image is (-18,0)

    Step-by-step 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)
