It can either have zero or one I think but I'm honestly not sure. I'm trying to figure it out my self right now.
None, one or an infinite number.In graph form, the three correspond to:None = Parallel linesOne = Interscting linesInfinite = Coincident lines.
Infinitely many. Assuming the variables are "x" and "y" , for every value of "x" a value for "y" can be calculated.
A.infinitely manyB.oneD.zero
Yes. You can obviously have a set of lines with no common intersection, can't you?
