    Answer:

    See explanation

    Step-by-step explanation:

    Assuming rectangle QRST has coordinates at T(2,-4), then we can find the coordinates of the image rectangle after a dilation by scale factor of 2 through the origin.

    We just multiply the coordinates of T by 2 to get the coordinates of of T’.

    T(2,-4)\to \: T'(2*2,2×-4)

    T(2,-4)\to \: T'(4, - 8)
