Circuit help

1. The problem statement, all variables and given/known data
I have a book problem that show this pic (see attachment)
The problem wants me to calculate Vo and the end point of the graph and midpoint but im not sure what Vo is.
2. Relevant equations

Vo=Va-Vb

3. The attempt at a solution
I think Vo is the total voltage of the power source so let say at the left end point of the graph we have (-4,-3) so because this is series i would say the total voltage was -7 for this point

rh23,
You are correct, Vo is sum of voltages across R and X.
