Answer: When a system of two linear equations gives an answer of
, there are infinitely many solutions. It also means that the graph represents parallel lines, so the answer is the third choice.
Step-by-step explanation: When it comes to systems of equations in algebra, you will see three types of solutions:
1. When you get an exact value & number for x and y, the system has one solution and is consistent/independent.
2. When you get
like in this case, the system has infinitely many solutions and is consistent/dependent.
3. When you get numbers that are not equal, for example,
, you have many solutions and the system is inconsistent/independent.
