To determine the sum of the two points on the number line, we need to know which specific points you are referring to. Since you haven't provided specific points, it's difficult to give an exact answer.
However, if we want to sum two points from the options provided, we can sum the two numeric values you provided:
- Consider the two points: -0.3 and 2.7
-0.3 + 2.7 = 2.4
- Or consider the points: 0.3 and -2.7
0.3 + (-2.7) = 0.3 - 2.7 = -2.4
Without specific points commonly referred to in a context, it's unclear which two to sum. Please clarify the points to get a precise answer.
