anonymous one year ago What is the equation of the line? https://static.k12.com/calms_media/media/1503500_1504000/1503770/1/1bf0d5d19875f8ba5b37c787b050508150a1633f/MS_IMC-140523-131301.jpg A. y = -3/2x B. y = -2/3x C. y = 2/3x D. y = 3/2x

1. anonymous

it is either a or d i m leaning to a though...

2. anonymous

plz put proof with ur work thx

3. anonymous

@Nnesha

4. anonymous

5. anonymous

how i cant see that...

6. anonymous

the x-axis is before the y-axis

7. Nnesha

A or D lets cancel out 2 options by just knowing this if the line is increasing then you will get positive slope if the line is decreasing then slope would be negative

8. anonymous

hmmmm... one sec

9. anonymous

oh so d? because the line is increasing

10. Nnesha

slope = rise over y-intercept is a point where line intersect y-axis so how many units it's going up from the y-intercept and then right ?

11. Nnesha

why is it D why not C ?

12. Nnesha

like i said line is increasing so A B can't be the answer

13. anonymous

ok, let me try c

14. anonymous

Take any 2 points that the line is passing through. I've taken (3,2) and (0,0). Then you use the standard line equation: (y-y1)={(y2-y1)/(x2-x1)}*(x-x1)

15. anonymous

Here: y1=2, x1=3, y2=0, x2=0.

16. anonymous

the line does not intercept with c

17. anonymous

WAIT!!!!!

18. anonymous

RISE TO RUN CORRECT???

19. Nnesha

$$\color{blue}{\text{Originally Posted by}}$$ @Houdini_Dragon the line does not intercept with c $$\color{blue}{\text{End of Quote}}$$ with x what do you mean ?

20. anonymous

2 up and 3 across

21. anonymous

i dunno why x is there that is just part of the answer choice

22. anonymous

perhaps it is because of the x-axis

23. Nnesha

y=mx+B is a slope intercept where m is slope and b is y-intercept x is variable with slope that supposed to be there

24. anonymous

u r right it is c, because the rise is 2, and the run is 3

25. anonymous

ok

26. Nnesha

|dw:1444338219047:dw| so yes right

27. anonymous

ah i should have known thank u @Nnesha

28. Nnesha

or as iphita7 mentioned you can pick two points and use formula to find slope

29. anonymous

Yup! Thank you @Nnesha for the graph!

30. anonymous

yes ans to @iphita7

31. anonymous

i may need more help in a bit i will tag if needed ;)
