Answer:
exactly one
Step-by-step explanation:
The system of linear equations have:
one solution, infinitely many solutions or no solution.
One solution if the lines intersect.
Infinitely many solutions if the lines are the same (overlap)
There is no solution if the lines are parallel (they do not have a common point).
In the graph, two lines intersect. Therefore, the system of equations has one solution (0, 3).
