anonymous one year ago Which of the following points satisfies the given graph? (0, -3), (1, -2) (2, 0) (3, 2)

1. anonymous

bout to post pic

2. anonymous

3. anonymous

i dont understand the question

4. anonymous

5. anonymous

6. skullpatrol

any ideas?

7. anonymous

no i thought it was all of them

8. anonymous

i mean if u graph them all they make the same line

9. skullpatrol

The phrase "satisfies" in math means is true for the graph.

10. anonymous

um i guess so

11. anonymous

if u graph the points it makes the same graph so, i guess they all satisfies

13. anonymous

well it doesnt make a straight line

14. anonymous

15. anonymous

hm so it would be the first ..slope right

16. anonymous

cause thats the only place its not the same

17. anonymous

(0, -3), is the only one that doesnt satisfies it

18. skullpatrol

So are you sure that the those two points satisfy the graph?

19. anonymous

no 3 points do...(0,3) is the only one that doesnt satisfies it

21. anonymous

oh

22. anonymous

(0,-3) does, (2,0) does, (3,2) does but (1,-2) doesnt

23. anonymous

24. skullpatrol

how do you know about the other two?

25. anonymous

cause i looked at these 2 pics, and (1,-2) doesnt match the graph given

26. anonymous

if u took (1,-2) out it would satisfie it

27. anonymous

right?

28. skullpatrol

29. anonymous

but doesnt (3,2) satisfies it to)

30. anonymous

cause its on the line

31. skullpatrol

|dw:1434319984011:dw|

32. anonymous

its the same thing u just posted,but doesnt (3,2) satisfies it to),cause its on the line right?

33. skullpatrol

I am trying to prove it for you :)

34. anonymous

cant u just say yer or no cause i dont undersstand your proof

35. skullpatrol

Now the ratio rise/run is called the slope m for this graph it is 3/2 we get an equation in the form y = mx + b by using b as the y-intercept which for this graph is (0, -3)

36. anonymous

nevermind i will figure it out

37. skullpatrol

We now have the equation y =(3/2)x - 3 all points that satisfy the graph will satisfy this equation

38. anonymous

does (3,2) satisfy this graph YES OR NO imple question

40. anonymous

yes or no

41. anonymous

wasted over 30 min

42. skullpatrol

43. skullpatrol

answer: ( 3, 2 ) no

44. anonymous

thank you

45. skullpatrol

Try ( 1, -2 ) for yourself please :)

answer ( 1 , -2 ) no
