Answer: (18, 2)

We find this answer by multiplying the original coordinates by the scale factor 2.

The old x coordinate 9 doubles to 9*2 = 18, which is the new x coordinate.

The old y coordinate 1 doubles to 1*2 = 2, which is the new y coordinate.

The dilation rule can be stated as
(x,y) \to (2x,2y), which means
(9,1) \to (18,2)
