## ineedyouubiebs 2 years ago Question attached!

1. ~Chance~

Neither do I @ineedyouubiebs

2. ineedyouubiebs

Sorry wait a sec I lost connection for a sec

3. ineedyouubiebs

Graph the equation of the line that intersects the coordinate (-3,-1) and has a slope of. 1/4

4. ineedyouubiebs

@~Chance~ there it is(:

5. ~Chance~

@Zale101 Hey she put it up!

6. ineedyouubiebs

I taught it was y=mx+b

7. Zale101

oh wait, do this formula y=mx+b and plug in the nimbers m is the slope b is the y intercept

8. Zale101

ya ur correct

9. Zale101

do u know how to plug in the numbers for that formula?

10. ineedyouubiebs

Yes I think I do, is it y=-3/4x-1 ?

11. Zale101

from where is -3/4?

12. ineedyouubiebs

Well I plugged it in like y=1/4(-3)-1 and I multiplied 1/4 and -3 and got -3/4

13. ineedyouubiebs

That's what I did

14. Zale101

hold on, let me check

15. Zale101

you have to get two lines in order to have an intersection point

16. Zale101

i think ur question should've been -1=1/4(-3)+b cuz the y coordinate is at -1

17. Zale101

m is the slope of the line and b is the y-intercept.

18. Zale101

x is the x coordinate given and y is the y coordinate given

19. ineedyouubiebs

Then it'll be -1=-3/4+b

20. Zale101

but u need to solve for b then

21. ineedyouubiebs

-1/4 =b

22. Zale101

yes

23. ineedyouubiebs

No. And after that how do I know where to graph?

24. Zale101

Then the line equation must be "y = 1/4x – 1/4".

25. Zale101

in slope intercept form

26. ineedyouubiebs

Can you try to graph it here so I can see I'm on my iPad right nowadays can't use the tools

27. Zale101

sure

28. Zale101

do u know how to find the solutions and get the ordered pairs ?

29. ineedyouubiebs

Yes

30. ineedyouubiebs

@Zale101

31. Zale101

can i ask u a question? Do u know how to use this formula?

32. ineedyouubiebs

Yes I do I just got confused that's all

33. Zale101

the answer became confusing when we started doing the y=mx+b formula

34. ineedyouubiebs

Yeah it did

35. ineedyouubiebs

I've never heard of that formula before

36. Zale101

oh wait, that's not true if there's two coordinates we first do the the slope (y2 - y1) / (x2 - x1) and then put it in y=mx+b, sorry wrong formula

37. Zale101

(y-y1)=m(x-x1) (y--1)=1(x--3) y=1x--3+-1 y=1x+2 1x-y+2=0 here's what i got for the point-slope formula

38. Zale101

and the way we graph it was y=x+2

39. ineedyouubiebs

They havnt taught me this so this is new to me

40. Zale101

do u have a math text-book with u?

41. Zale101

maybe the formula is near the chapter ur currently on

42. Zale101

if i were to use y=mx+b, the graph is y=1x-1

43. ineedyouubiebs

I think I got. My older sister helped me with. Thank you so much for your help though. I appreciate it(:

44. Zale101

no problem, is the answer y=1x-1?

45. ineedyouubiebs

Yup

46. Zale101

so we were right before :)

47. ineedyouubiebs

Yeah we were
