    good!!! they have different slope --> they intersect at some where. With 2 lines: only possibilities: 1) // (no solution) 2) exactly the same (many solutions) \3) 1 solution No way to get 2 solutions.

    Algebraic way: \(\begin{cases}x+y=2\\2x+y=4\end{cases}\) subtract them together x = 2, hence y = 0

    K that's better! That's why I need to know because some people give wrong answers.

    ok!! whatever, as long as you want to study, I am ok. Don't take the free answer. It's not good for the long run
