To find the coordinates A' and B' after a dilation with a scale factor of 2, centered at the origin, we multiply the x and y coordinates of points A and B by the scale factor.

For point A(3,7):
x-coordinate of A' = 3 * 2 = 6
y-coordinate of A' = 7 * 2 = 14

Therefore, A' = (6,14)

For point B(4,9):
x-coordinate of B' = 4 * 2 = 8
y-coordinate of B' = 9 * 2 = 18

Therefore, B' = (8,18)

The correct answer is A' = (6,14) and B' = (8,18).
