Because this is a straight line, and not a vertical line, the domain is all real values. This is because IF you solved for y, you would get a formula for y in which any value of x would be allowed. There are no restrictions on the values of x.

Another thought, if you picture the graph of any straight line (non-vertical, that is!), the graph reaches all the way to the left and all the way to the right, with no breaks in the line.
graph%28+300%2C+300%2C+-10%2C+10%2C+-10%2C+10%2C+%283x-13%29%2F7+%29+
Therefore all values of x are allowed.

The correct answer is 1. Set of real numbers!
