To find the coordinates of A' and B' after a dilation with a scale factor of 12, centered at the origin, we can multiply the x and y coordinates of A and B by the scale factor.
For A (-6, 4):
The x-coordinate of A' is -6 * 12 = -72
The y-coordinate of A' is 4 * 12 = 48
So the coordinates of A' are (-72, 48)
For B (-8, 2):
The x-coordinate of B' is -8 * 12 = -96
The y-coordinate of B' is 2 * 12 = 24
So the coordinates of B' are (-96, 24)
