## kathrynjones2015 2 years ago I give medals and fans LINE OF BEST FIT HELP PLEASE Which equation BEST represents the line of best fit for the scatterplot? y - x = 2 y= x + 1 y -x = -2 y = 2x + 1

Whats the Y value?

3. bloodrain

Try looking here for help, its what helped me with this: http://www.regentsprep.org/Regents/math/ALGEBRA/AD4/linefit.htm

4. jperez570

What is the approximate slope?

5. Nargiss

is that for me bloodrain?

6. bloodrain

Yes, look at that website for help because I remember it really helped me. Its a really good guide.

7. Nargiss

thank you bloodrain

8. jperez570

Since you have the answer as multiple choice, what equation describes the graph best?

9. kathrynjones2015

I think it's either the first answer choice or the last answer choice, but I'm not sure and I need to make a good grade on this quiz..

10. jperez570

y int is positive 2 so now find the slope 1/1 *hint, cough, cough*

11. jperez570

x+2 *cough, cough*

12. bloodrain

I believe it is A

13. kathrynjones2015

Can you explain it to me please?

14. bloodrain

Alright, you know what the line of best fit is right?

15. kathrynjones2015

Yes.

16. bloodrain

OK, to prove that it is A. You can make a graph of it with a graphing calculator. You have one?

17. kathrynjones2015

Yep I sure do !

18. bloodrain

OK, graph the equation in A and it will prove the answer

19. kathrynjones2015

Oh my, thank you SO much !

20. bloodrain

yeah its that simple, now remember that for the next time you have to do this :D
