Hmm so it's pretty much the same type of problem as we did before :O
Do you know how to graph each of these lines?

anonymous · Answer

we are still using y=mx+b and uhh brain fart

anonymous · Answer

Im sorry i just have a ton of work to do

zepdrix · Answer

heh

zepdrix · Answer

The lines will cross the y-axis at the b values.

anonymous · Answer

Got it! and the b value is 1 for the first one correct?

anonymous · Answer

YAY! I finally get something lol

zepdrix · Answer

Hmm so we need another point on this line.$$\large y=\frac{1}{3}x+1$$What would be a good x value that we can plug in?
We want to plug in a value that will deal with the fraction nicely.

anonymous · Answer

hmm

zepdrix · Answer

We have a 1/3.. hmmm

What happens to the 1/3 if we plug in x=3?

anonymous · Answer

OMGGG ! i was trying it to make sure it fit. sounds good.. we'll get 2

zepdrix · Answer

|dw:1369397113105:dw|Ok good! That gives us another point on our line.
Now we can draw the line through these two points.
