What is the slope of a line? Can you define it?

3. xoxo Group Title

its under the attachment

4. RyanL. Group Title

The person is asking you if you know what a slope is.

5. the_lefay Group Title

Lol, I have seen the attachment, and I know the answer, but I want you to understand it

6. the_lefay Group Title

Thanks RyanL lol

7. xoxo Group Title

I do not understand this question... and i posted it here because I wanted an explanation. can you please help me.. thank you!

8. RyanL. Group Title

Umm one explanation is$\frac{rise}{run}=slope$ Where you pick two point and determine how much you need to travel to get one point to the other Rise would be how high or low you go Run is how far you go to the left or right.

9. xoxo Group Title

ohhh but i still dont get it

10. RyanL. Group Title

What don't you get? Do you know how to count?

11. RyanL. Group Title

Do you even know how to divide?

12. RyanL. Group Title

|dw:1345071480215:dw|so you know what that is?

13. RyanL. Group Title

14. xoxo Group Title

i am not a baby miss lefay

15. the_lefay Group Title

The slope of a line is the "rise" divided by the "run", meaning how high you go up the y-axis divided by how far you run down the x- axis

16. xoxo Group Title

yes i understand that part

17. xoxo Group Title

but its so confusing how do you go up then go to the left!

18. the_lefay Group Title

Um, I didn't call you a baby or mean to insult you. If you're insulted then I apologize.

19. RyanL. Group Title

20. RyanL. Group Title

See the lines i drew. How many times does it go down and how many times does it go to the right?

21. the_lefay Group Title

Imagine you are driving your car from the origin (0, 0). You drive straight up the y-axis, and then you turn right on the x-axis

22. xoxo Group Title

okay

23. the_lefay Group Title

I'll let RyanL handle this one... He's taking you in the right direction xoxo

24. RyanL. Group Title

From (0,3) to (0,0) how many times did we move?

25. xoxo Group Title

ryan why are you so mean

26. xoxo Group Title

i was in need of help and yet you were asking someone clueless girl if they know how to divide of course i know the basics

27. xoxo Group Title

i think you moved 3 spaces

28. RyanL. Group Title

Yes you are correct but since you moved 3 spaces down it's a negative -3 so rise= -3 Write that down.

29. RyanL. Group Title

Now from (0,0) to (9,0) how many spaces do you move?

30. xoxo Group Title

9 spaces

31. RyanL. Group Title

Yes and since we are going to the right this time it will be positive so run=9

32. xoxo Group Title

okay and do yuou divide after?

33. RyanL. Group Title

$\frac{rise}{run}$ Now plug those values into the fraction

34. RyanL. Group Title

and what do you get?

35. xoxo Group Title

-3/9

36. xoxo Group Title

is that it -1/3?

37. RyanL. Group Title

yes but you can also simplify that

38. RyanL. Group Title

$\frac{-3}{9}=\frac{-3}{3*3}$

39. RyanL. Group Title

A three from the top cancels one from the bottom

40. xoxo Group Title

i know

41. RyanL. Group Title

what do you get then?

42. xoxo Group Title

how do you simplify -1/3! Ryan

43. RyanL. Group Title

Now you can't I told you have to simplify -3/9

44. RyanL. Group Title

I thought you didnt know hot to do that that's why

45. xoxo Group Title

ugh im not that stupid!

46. RyanL. Group Title

Sorry I don't know what level of math you are in so sorry

47. xoxo Group Title

no you were being a jerk

48. RyanL. Group Title

I'm not being a jerk. I helped you out and this is how you respond?

49. xoxo Group Title

no no im thankful but you were being really mean

50. RyanL. Group Title

Sorry I didn't see that you wrote -1/3 until after I went up to see it.

51. RyanL. Group Title

I only saw that you wrote -3/9 my bad

52. xoxo Group Title

Are u in college

53. RyanL. Group Title

yup yup!

54. xoxo Group Title

see thats why im in high school so there is a differece

55. RyanL. Group Title

It's ok I remember when I had problems in HS and I still do. Math is not easy so be happy that you can do this type of work. For some people it's even harder. Good job!
