Actually, you can't: #x=2.7# isn't even a function, because it's a vertical line. This means that you are giving infinite values of #y# to a single value of #x#, while you should give one, and one only value of #y# for each #x# in the domain.

The only way for answering this question is considering the #x# as a function of #y#, while we usually do the opposite. By doing so, #x=2.7# would be a constant function, and would thus have slope equal to #0#.
