## Taylor0402 one year ago What is the equation of the graphed line? A. y=-2x B. y=-1/2x C. y=1/2x D.y=2 x

y=mx+b slope intercept form where m is slope and b is y-intercept if line increasing then slope would be positive  if line is decreasing then slope would be negative slope = rise over run (count how many units its going up from the y-intercept and then how many units to the right ) b(y-intercept) is a point where line intersect at y-axis

4. Taylor0402

so its a positive number right...this is just really confusing for me

5. Nnesha

right slope would be positive bec line is increasing

6. Taylor0402

i just cant tell if the line is increasing or decreasing

7. Nnesha

heck your options are sure they are correct ?

8. Nnesha

check ** sorry not that word

9. Taylor0402

yes that is what they gave me

10. Nnesha

then graph doesn't go with that options

11. Taylor0402

i just can never tell hat way the slope is going how do i know it is going up or down...and after i figure that out i newere know which answer it is

12. Taylor0402

if you had to pick the best answer what would it be

13. Nnesha

alright |dw:1444308980484:dw| if the line coming from 2nd quadrant to 4th then the line is decreasing

14. Nnesha

|dw:1444309061792:dw| if the line is coming from 3rd quadrant to 1st then line increasing

15. Taylor0402

oh ok got it

16. Taylor0402

so the number has to be a negative

17. Taylor0402

so it would be either a or b

18. Nnesha

hmm why ?

19. Nnesha

so is the line increasing or decreasing in ur graph ?

20. Taylor0402

it is decreasing from my graph and as you said towards the top that decreasing is negative

21. Nnesha

22. Taylor0402

now im confused :(

23. Nnesha

|dw:1444309368772:dw|if the line coming from 2nd quadrant to 4th then the line is decreasing

24. Nnesha

|dw:1444309392229:dw|if the line is coming from 3rd quadrant to 1st then line increasing

25. Taylor0402

yes so the number would be a negitive right? =)

26. anonymous

y = 1/6+0

27. Nnesha

|dw:1444309473751:dw| line is increasing or decreasing ?

28. Taylor0402

OMG i am so sorry i put the wrong picture up and i didnt even notice it is this one

29. Nnesha

see i told you

30. Nnesha

$$\color{blue}{\text{Originally Posted by}}$$ @Nnesha then graph doesn't go with that options $$\color{blue}{\text{End of Quote}}$$

31. Taylor0402

that was from my last question...i am so sorry

32. Nnesha

it's okay.

33. Taylor0402

i will get the other one for you right now...ugh i feel so stupid :(

34. Taylor0402

35. Taylor0402

there it is...now i know this is the right one

36. Nnesha

|dw:1444309675527:dw| aw then yes line is decreasing slope would be negative

37. Nnesha

now find y-intercept y-intercept is a point where line intersect at y-axis

38. Taylor0402

ok thats what i thought...now I feel smart again :)

39. Nnesha

hahah yes you are smart!

40. Taylor0402

no i am really bad at math you are the smart one here...if you were not helping rn i would get this wrong

41. Taylor0402

it would be -2 right

42. Nnesha

hmm slope is rise over run so how many units its going down from the yintercept

43. Taylor0402

oops it would be -1/2

44. Nnesha

|dw:1444309931152:dw|

45. Taylor0402

oh so thats what rise over run is

46. Taylor0402

would it be 2

47. Nnesha

how is it 2 ? please explain how many units its going down from y-intercept ??

48. Taylor0402

-4 but thats not an answer

49. Nnesha

|dw:1444310141486:dw|

50. Nnesha

right rise = -4 but we also need run so what's run

51. Nnesha

how many units it's going to the right side ?

52. Taylor0402

ok i would say -2

53. Nnesha

right side where x values are positive so rise =-4 and run =2 slope = rise over run replace rise with -4 and run with 2 and then divide

54. Nnesha

$\rm slope =\frac{ rise }{ run }=\frac{ -4 }{ 2 }$

55. Taylor0402

56. Nnesha

right :=)

57. Taylor0402

OMG thank you sooooo much

58. Nnesha

np

59. Taylor0402

if you ever need help on a question ( any subject but math) i would be glad to help

60. Taylor0402

i am going to close this question but i have one more i need that i cant get

61. Taylor0402

i will tag you in it

62. Nnesha

alright and yes sure i will tag u when i need help thanks ! :=)
