Question

[6.01] You graph a system of equations and the two lines overlap, or lie right on top of one another. Explain what this tells you about the:

solution to the system
the two equations
the result if the system was solved algebraically

I got
1.Infinite solutions
2. y=x+6; y=x+6
3.x=x

Am I right?

Answer 1

(3) of course x=x. It's like saying 2=2!

Answer 2

But is it right?

Answer 3

there are infinite solutions

Answer 4

Of course. Imagine a line but equal. f(x)=f(x).

Answer 5

ohhh ok thanks
