What is 'the same'?
Explained below in detail.
Negative sign in front of what?
In front of the number of sheep he owes (Can be seen as X). The overall function of the shepherd owning or being in debt of sheep does not matter except on the graph by which the line on the Y-axis spans from a negative value instead of positive.
How much sheep does the shepherd owe his neighbor, or is it unknown?
How much sheep does the shepherd have to start with, or is it unknown?
It is unknown. You are supposed to plot an asymptote to represent the function on self explanatory points. On X1 = 5 and X2 = 10 then the asymptote in between might be (2x²)/3 for instance. Plotting the whole graph instead is acceptable, but will be looked down upon.
