Question

We are doing the linear graph words typed over time. We have the average words and the times. Do I need to include 0,0???

Answer 1

i wouldn't, i'd exclude it becuase its not truly a data point.

Answer 2

But, it is kind of a data point. Time presumably starts at 0, and at 0 there are no words that have been typed. Maybe I'm wrong.

Answer 3

no, I can see what you are saying.
another way to think about it is consider making '0' the first reading you got, so pretend if I had 8 as my value of my first reading. then I wouldn't plot it as
(0,0) and (1,8)
i would plot it as
(0,8)
make sense?

Answer 4

Wouldn't it depend entirely on whether or not his equation has a c value? since in \[y=mx+b\]
When x=0, the point is 0,b.

Answer 5

I have no idea. The lab sheet asks whether we should use it or not. I can see what both of you are saying. It does make a big diff on the equation.

Answer 6

right, if he had a 'c' value, then you are spot-on, but in this case, he doesn't have a 'c' value becuase he is asking if (0,0) is included in the number set.

Answer 7

you can do what you want, but if it were me, I would shift all my 'x' values by 1, so my first y value on my graph isn't 0.

Answer 8

Hmm. If you want to impress the teacher maybe you should say that it depends on what the equation for the line was.

Answer 9

After talking to other class members, we feel it is appropriate to use 0,0.
If the equation was y=1.297x-.97, it is right to say that for every extra second given, 1.297 words were typed?

Answer 10

Using 0,0 would be incorrect in this case.

Answer 11

Because if the x value is 0 then the point would be (0,-.97)

Answer 12

But yes It is correct to say that.

Answer 13

I see what your saying abut the 0.-.97.... humm...

Answer 14

That's messed up.

Answer 15

Why would they put something that's wrong in the question.
