What does the number of solutions of a system of linear equations represent ?

the places where the linear graphs meet are at the same point

The solution is the point of intersection between the lines in the equation. Parallel lines have no solution, that is, they never intersect. Dependent systems are the same line so every solution of the first line is a solution of the other line, hence infinite number of solutions.

Step-by-step explanation:
