## tayluvsya 2 years ago how do u find the slope

1. myininaya

What are you given to find the slope?

2. Yahoo!

of a Line Ryt ?

3. Yahoo!

o.O

4. tayluvsya

(1,-4) _(-4,2)

5. myininaya

If given two points on a line, then use the slope formula: $m=\frac{y_2-y_1}{x_2-x_1}$

6. hba

Well you can check my tutorial http://openstudy.com/study#/updates/50aa93b5e4b06b5e493312f5

7. tayluvsya

ok

8. tayluvsya

it dont help

9. tayluvsya

?????????

10. cv2001

A slope is the change in Y over the change in X. In other words, the incline or decline of a line. In this case, the line suggested by these points has a slope of (8+5), the change in Y divided by (-4+5), the change in X 13/1 = 13

11. cv2001

hope that helps

12. tayluvsya

kinda

13. cv2001

That gives you slope. To remember that it's "rise over run." (-5-8)/(-4+3)...which would be 13/1...so that's up 13 units and to the right 1.

14. cv2001

does it help now

15. skullpatrol

What don't you understand about slope?

16. tayluvsya

which numbers go to what

17. tayluvsya

skull can u fan me cuz i need to message u

18. skullpatrol

OK

19. tayluvsya

thnks

20. skullpatrol

Do you want to learn about slope?

21. skullpatrol

|dw:1357744036921:dw|

22. skullpatrol

Do you know how I plotted the points?

23. tayluvsya

yes

24. tayluvsya

thnks

25. skullpatrol

Now we connect the two points with a straight line and find the slope.

26. skullpatrol

|dw:1357744632127:dw|

27. skullpatrol

Label one point "2" and the other "1"

28. skullpatrol

|dw:1357744730852:dw|

29. skullpatrol

|dw:1357744805464:dw|

30. skullpatrol

Any questions so far?

31. tayluvsya

so if its A it will be the 1s

32. skullpatrol

What is "A"?

33. tayluvsya

34. tayluvsya

|dw:1357744800797:dw|

35. tayluvsya

the points and dont laugh at my drawing

36. skullpatrol

|dw:1357745099709:dw|

37. skullpatrol

Yes!

38. tayluvsya

ok

39. skullpatrol

It doesn't matter which point you label "A" or "B".

40. tayluvsya

ok

41. tayluvsya

brb

42. tayluvsya

k back

43. skullpatrol

|dw:1357745356883:dw|

44. skullpatrol

|dw:1357745621032:dw|

45. tayluvsya

so it goes like this|dw:1357745633210:dw|

46. skullpatrol

Excellent!

47. skullpatrol

|dw:1357746023149:dw|

48. tayluvsya

so it will be |dw:1357745819919:dw|

49. tayluvsya

??

50. skullpatrol

51. tayluvsya

the slopes right

52. skullpatrol

|dw:1357746331429:dw|

53. tayluvsya

|dw:1357746144509:dw|

54. skullpatrol

|dw:1357746405461:dw|

55. skullpatrol

Yes.

56. tayluvsya

|dw:1357746289688:dw|

57. tayluvsya

right?

58. skullpatrol

Almost, you should simplify it.

59. tayluvsya

|dw:1357746415641:dw|

60. skullpatrol

Yes!

61. tayluvsya

yay

62. skullpatrol

|dw:1357746884797:dw|

63. skullpatrol

Now the "slope intercept" form of the equation of this line is y = mx + b where b is the y-intercept.

64. tayluvsya

???

65. skullpatrol

Have you not covered the equation of a line yet?

66. skullpatrol

y = 6x + 2

67. tayluvsya

???

68. tayluvsya

i dont get it

69. skullpatrol

|dw:1357747357912:dw|

70. hba

Slope is actually the rise over run of a function :)

71. tayluvsya

ok now i think i get it

72. tayluvsya

thnks skull

73. skullpatrol

np

74. tayluvsya

:)

75. tayluvsya

how do u post another math question?

76. tayluvsya

skull

77. tayluvsya

??????????

78. phi

79. tayluvsya

thnks

80. tayluvsya

:'(

81. skullpatrol

No, I'm not.

82. tayluvsya

u unfanned me so i cant message u

83. skullpatrol

84. tayluvsya

i wanted to be friends

85. tayluvsya

k idc

86. skullpatrol

You can ask me for math help any time :-D

87. tayluvsya

it says i cant

88. tayluvsya

u have 55 fans i cant be one

89. skullpatrol

ok I'll fan u

90. tayluvsya
