The solution of the graphs are
1. Infinitely many solutions
2. No real solutions
3. (-1, 2)
How to find the solution of graphs
The solution of linear equations is the point where the two lines graphed intersect.
The answers are found as follows
In the first graph, the two lines are overlapping, hence we say the solution is infinitely many solution
In the second graph, the equation represents a parallel line and the solution in this case is no real solution.
In the third graph, the intersect is located at point (-1, 2) and hence the solution
