anonymous one year ago X-y=3 find 3 order pairs and graph

1. pooja195

Well what numbers make 3?

2. anonymous

1+2

3. pooja195

Careful its subtraction

4. pooja195

5. pooja195

__ - __ = 3

6. anonymous

-2-1

7. pooja195

That would be -3

8. pooja195

How about 3-0? what is 3-0=?

9. anonymous

3-0

10. anonymous

3

11. pooja195

Good that takes care of one coordinate (3,0) what else?

12. anonymous

1-2

13. pooja195

That makes -3 Use larger numbers

14. anonymous

5-2

15. pooja195

good! so now we have (3,0) (5,2) one more...!!

16. anonymous

6-3

17. pooja195

good so (6,3) (3,0) (5,2) to graph them i recommend you use this: https://www.desmos.com/calculator

The x coordinates must contain 3,1, and another number

20. pooja195

What do you mean?

21. pooja195

Is there a way you can screenshot the question?

22. anonymous

Complete the table x 3, 1, and ? Y 0,? ,-1 Which should be equal to x-y=3

23. pooja195

|dw:1442777008623:dw|

24. pooja195

So like this?

25. anonymous

Yes

26. pooja195

ok so lets start with the x value from the bottom ___ - -1=3 OR ___ + 1 = 3 what goes in the blank?

27. anonymous

2

28. pooja195

keeping in mind that a negative and a negative together make a postiive

29. pooja195

ok so now we have |dw:1442777253862:dw|

30. pooja195

any ideas for the y value for this one? |dw:1442777299670:dw|

31. anonymous

So they answers for y is 0,2, and -1

32. pooja195

33. anonymous

2

34. anonymous

-2

35. anonymous

Refer to the attachment

36. pooja195

good so now we have |dw:1442777445636:dw|

37. pooja195

(3,0) (1,-2) and (2,-1) are the 3 coordinates you should use a graphing online tool to help you graph it out because im not really sure how to help you with that part use this site: https://www.desmos.com/calculator

38. pooja195

Any questions?

39. Nnesha

or you can substitute x value then solve for y( if you are not good at guessing ) $\huge\rm x-y=3$ substitute x for 1 solve for y$\large\rm 1-y=3$ to cancel out one from left side subtract one both sides  $\color{ReD}{-1}+1-y=3\color{ReD}{-1}$ at left sides 1 cancels out $-y=2$ to cancel out negative sign multiply or divide by sides by -1$-1 \times -1y=2 \times -1$(negative times negative =positive , negative times positive =negative ) you will get y=-2

40. pooja195

You still get the same answer either way.

Thanks to all
