The graph was clearly the direct relationship. As temperature increases, pressure increases in a linear fashion. It has nothing to do with an asymptote. Plus, it cannot go negative because the graph shown is only the first quadrant. You overthought the question.
@jacobreis It is equal. It is true that one had 2 Hydrogens and the other only had one hydroxide but what they wanted you to say was that a neutral solution has equal amounts of the two ions, making a pH of 7.
