Question

1. How do you graph the solution set to a system of linear inequalities in two variables?

2. How do you determine whether a system of linear equations has no solution, one
solution, or infinitely many solutions?

Answer 1

I can answer #2
No solution: The lines on the graph would show up as parallell
One Solution: The lines on the graph would have one meeting point
Infinitely many solutions: The lines would be overlapping each other 
Hope this helps :)
