Answer: (x,y)->(2x, 2y)
Step-by-step explanation: When figure ABCD is dilated by a scale factor of 2, the coordinates of all the points in the dilated figure are multiplied by 2. If (x, y) is any point on the original figure that gets dilated by a scale factor of 2, then the expression that represents the coordinates of this point in the dilated figure is given by (2x, 2y).
