Answer 5

bottom line, 3 things are possible
1) the two lines are going to cross once and that solution is the location
2) two lines are parallel and they do not cross, we call that "no solution"
3) both lines overlap each other and since they cross in many places
we say that it is "infinitely many solutions."

Answer 6

also, if I had to pick one method, I would pick elimination.
