Question

[6.01] You graph a system of equations and get two lines that are parallel. Explain what this tells you about the:

1.solution to the system
2.the two equations
3.the result if the system was solved algebraically

anonymous · Answer

There is a solution to the system if the lines cross each other. 
Do parallel lines ever cross each other?

anonymous · Answer

no they dnt

anonymous · Answer

Great so there is no solution for parallel lines. That is the answer for the first one.

anonymous · Answer

What can you tell me of the slope of two parallel lines?

anonymous · Answer

there the same ? right ?

anonymous · Answer

Yes you are correct. So if you set up both equations in this form

y=mx+b

where m is the slope we will know that both equations will have the same m

anonymous · Answer

That's for the second part. Not sure about the last. We also know that they don't have a solution

anonymous · Answer

We can try to solve it but we will not get an answer.


It will end up something in the lines of 

0=some number other than zero

and we know that 0 can't equal a number so that means there is no solution.

I think that's what it means.....idk hope I helped you out.
