Although there is no graph, the number of solutions is 0.

The set of points the graphed equations have in common. This is usually a single point but the lines can be coincident in which case the solution is a line or they can be parallel in which case there are no solutions to represent.
A system of equations means that there are more than one equations. The answer depends on the exact function(s).
A system of equations will have no solutions if the line they represent are parallel. Remember that the solution of a system of equations is physically represented by the intersection point of the two lines. If the lines don't intersect (parallel) then there can be no solution.
It means that the equations are actually both the same one. When they're graphed, they both turn out to be the same line.
If you refer to linear equations, graphed as straight lines, two inconsistent equations would result in two parallel lines.
If a system of equations is inconsistent, there are no solutions.
The graph is not visible and so it is not possible to tell whether the lines are in a space with 2 dimensions or more. In 2-d space there is one solution whereas in more dimensions there may be none or one.
no.
y = mx + b y = mx + c c does not equal b the two equations are parallel and will therefore never intersect with one another.
As there is no system of equations shown, there are zero solutions.
