Question

How does graphing the solution help you to be sure you have correct solution?

Answer 1

It’s just a way of checking your answer, like using a calculator, if you graph something (correctly) and compare your answer (something that can be graphed) to your graphed number you can check your answer

Answer 2

It helps you see the visual move of what you were doing. If you weren't moving anything it would help you see if it is true or false. Say you put a dot on the origin (0,0), then you have to go (x+7,y+3) then moving it on a graph would help show you. So overall it's a visual help to people.
