Question

The table gives the population of a town for the years 2000-2009.

Answer 1

Continuation from last question because it got really slow...

Answer 2

Can anyone help...

Answer 3

Please...

Answer 4

I don't understand how to make the equation so far all I have is 2050=50 (2005) +B

Answer 5

And I dont want the answer I want to know how to do it

Answer 6

Did you plot the points?

Answer 7

Yes

Answer 8

Did you then try to fit a line?

Answer 9

Yes I did all that I got the line and the slope and I plotted now all I need to do is find out how to solve the equation.

Answer 10

For some weird reason when I plug it into a calculator it says -98200 and I don't believe that is correct.

Answer 11

Ok.
How did you get the slope of the line?

Answer 12

If you look at the attachment I got the slope of the line from they year 2005 and 2007

Answer 13

I used points 2005, 2050
and 2150, 2007

Answer 14

Ok.
The way to do this is:
1. Plot every point.
2. Fit a line.
3. Using two points on the best fit line, find the slope.
4. Then use the slope and any point on the line to find the equation of the line.

Answer 15

Thought I'd jump into this lengthy topic and post a graph I made.

Answer 16

I did all that I used the equation \[Y2-Y1/X2-X1\]

Answer 17

Thank you wolf :D

Answer 18

The line of best fit is found by first, plotting all points.
Then you conect the points with segments.
To get the line of best fit, you need to place a line, so that the area on one side of the line equals the area on the other side of the line.

Answer 19

I did that want me to show you the line I made?

Answer 20

The slope and equation are of the line of best fit, not of any points that were plotted, unless, of course, by coincindence, some of the plotted points are on the line of best fit.

Answer 21

Well some are actually...

Answer 22

But the line of best fit is supposed to go between them isn't it?
