You graph a system of linear equations and the solution appears to be (3,4). How can you verify that the solution is (3,4)?

Question

I was not at school. I need some help because they took notes and I was not there, and so they assigned homeowkr and I do not know what to do.

Answer 1

Tre, see my answer to your other question, especially my note at the end, and see if you can formulate an answer. It's not that different from any other equation. If you graphed a line and the y-intercept appeared to be 3, how could you be sure?
