======================================================

Step-by-step explanation:

The x coordinate of the preimage point Q is x = 6.

The x coordinate of the image point Q' is x = 21.

The ratio of image over preimage is 21/6 = (3*7)/(3*2) = 7/2

You'll get this same value if you do the same steps with the y coordinates.

Therefore, the scale factor is 7/2 and the dilation rule is
$(x,y) \to \left((7)/(2)x, (7)/(2)y\right)$

Note: 7/2 = 3.5
