## xoxo 3 years ago Choose the correct slope of the line shown on the graph below.

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

3. xoxo

its under the attachment

4. RyanL.

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

5. the_lefay

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

6. the_lefay

Thanks RyanL lol

7. xoxo

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.

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

ohhh but i still dont get it

10. RyanL.

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

11. RyanL.

Do you even know how to divide?

12. RyanL.

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

13. RyanL.

14. xoxo

i am not a baby miss lefay

15. the_lefay

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

yes i understand that part

17. xoxo

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

18. the_lefay

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

19. RyanL.

20. RyanL.

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

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

okay

23. the_lefay

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

24. RyanL.

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

25. xoxo

ryan why are you so mean

26. xoxo

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

i think you moved 3 spaces

28. RyanL.

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

29. RyanL.

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

30. xoxo

9 spaces

31. RyanL.

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

32. xoxo

okay and do yuou divide after?

33. RyanL.

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

34. RyanL.

and what do you get?

35. xoxo

-3/9

36. xoxo

is that it -1/3?

37. RyanL.

yes but you can also simplify that

38. RyanL.

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

39. RyanL.

A three from the top cancels one from the bottom

40. xoxo

i know

41. RyanL.

what do you get then?

42. xoxo

how do you simplify -1/3! Ryan

43. RyanL.

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

44. RyanL.

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

45. xoxo

ugh im not that stupid!

46. RyanL.

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

47. xoxo

no you were being a jerk

48. RyanL.

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

49. xoxo

no no im thankful but you were being really mean

50. RyanL.

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

51. RyanL.

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

52. xoxo

Are u in college

53. RyanL.

yup yup!

54. xoxo

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

55. RyanL.

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!
