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

3. anonymous

its under the attachment

4. anonymous

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

5. anonymous

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

6. anonymous

Thanks RyanL lol

7. anonymous

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

8. anonymous

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. anonymous

ohhh but i still dont get it

10. anonymous

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

11. anonymous

Do you even know how to divide?

12. anonymous

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

13. anonymous

14. anonymous

i am not a baby miss lefay

15. anonymous

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. anonymous

yes i understand that part

17. anonymous

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

18. anonymous

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

19. anonymous

20. anonymous

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

21. anonymous

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. anonymous

okay

23. anonymous

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

24. anonymous

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

25. anonymous

ryan why are you so mean

26. anonymous

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. anonymous

i think you moved 3 spaces

28. anonymous

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

29. anonymous

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

30. anonymous

9 spaces

31. anonymous

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

32. anonymous

okay and do yuou divide after?

33. anonymous

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

34. anonymous

and what do you get?

35. anonymous

-3/9

36. anonymous

is that it -1/3?

37. anonymous

yes but you can also simplify that

38. anonymous

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

39. anonymous

A three from the top cancels one from the bottom

40. anonymous

i know

41. anonymous

what do you get then?

42. anonymous

how do you simplify -1/3! Ryan

43. anonymous

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

44. anonymous

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

45. anonymous

ugh im not that stupid!

46. anonymous

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

47. anonymous

no you were being a jerk

48. anonymous

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

49. anonymous

no no im thankful but you were being really mean

50. anonymous

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

51. anonymous

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

52. anonymous

Are u in college

53. anonymous

yup yup!

54. anonymous

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

55. anonymous

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!
