Best ResponseYou've already chosen the best response.0if by "solutions" they mean points where they exist then all three are infinity. if they mean solutions as in intersecting points then A has none, B has none and C would be the corssing point of the two lines

Best ResponseYou've already chosen the best response.0Solutions to systems of equations are points which all equations have in common. So two parallel lines have no points in common (they never cross). A single line has only one equation and would thus have infinitely many solutions. Because it would have all it's points in common with itself. A pair of nonparallel lines would have only one solution because two nonparallel lines can only intersect at a single point.
