To express the given relation as a table, we can organize the pairs you provided along with the blank that needs to be filled. Here’s how the table will look:
| x | y | |-----|-----| | -4 | 5 | | 18 | 15 | | 18 | 5 |
Thus, the filled-in blank represents the point (18, 5). The completed table includes all the points from the relation you've provided.
