-----------
If you have two linear equations, and one is a multiple of the other,
the system is said to be dependent; the graph is a single line; every
point on the line is a solution for the system. That means there
are an infinite number of solutions if the system is dependent.
------------------------
If two linear equations have the same slope, the lines are parallel.
There is NO solution for the system.
NO solutions does not mean "0" is a solution. Zero is a number
just like any other number is a number. No solutions means there
are no solutions.
Cheers,
Stan H.
