anonymous · Answer

Can you graph lines? ^.^

anonymous · Answer

The asnwers that i got for x=2 and for y=-13/2
I'm about to submit any input will be greatly appreciated.
Thanks@

anonymous · Answer

graph yes I can.

anonymous · Answer

Okay, could you sketch the graph of

anonymous · Answer

it is asking me for x and y i am confused as to how to respond

anonymous · Answer

There we go ^.^

anonymous · Answer

Of course, You have to graph this line as well, and those two lines will intersect at your answer :)

anonymous · Answer

great work :)
and now, whatever coordinates this point is...|dw:1371350485617:dw|
that's your answer.

But then again, solving by graphing isn't the most accurate of ways to solve...
