Answer

The number cubes showed the same values on both rolls.

Work Step by Step

Since the point must be plotted on the origin, (0,0), the sum of the cubes on both rolls was 0. If one cube is positive and another cube is negative, we get zero when they are the same. For example: $$-4+4=0$$ This shows that both cubes showed a 4 when rolled.
