A vertical line #8# units to the right of the origin.

Explanation:

This is an odd graph.

Think about what it's saying: #x=8#. This means that NO MATTER WHAT, #x# HAS TO equal #8#.

Notice that #y# is not even mentioned in the equation. Therefore, #y# is irrelevant! The only thing that matters is that #x=8#.

Therefore, points you could plot would be anything in the form #(8,y)#. You could plot #(8,0),(8,-4),(8,61),# or #(8,-pi)#.

It would look like a vertical line:

Note that any graph #x=a# where #a# is just a number is a vertical line. Similarly, any graph of #y=a# is just a horizontal line.
