Good that takes care of one coordinate (3,0) what else?
anonymous
  • anonymous
1-2
pooja195
  • pooja195
That makes -3 Use larger numbers

6-3
pooja195
  • 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

What do you mean?

Is there a way you can screenshot the question?

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

|dw:1442777008623:dw|
pooja195
  • pooja195
So like this?
anonymous
  • anonymous
Yes
pooja195
  • pooja195
ok so lets start with the x value from the bottom ___ - -1=3 OR ___ + 1 = 3 what goes in the blank?
anonymous
  • anonymous
2
pooja195
  • pooja195
keeping in mind that a negative and a negative together make a postiive
pooja195
  • pooja195
ok so now we have |dw:1442777253862:dw|
pooja195
  • pooja195
any ideas for the y value for this one? |dw:1442777299670:dw|
anonymous
  • anonymous
So they answers for y is 0,2, and -1
pooja195
  • pooja195
dont worry about the answer atm just answer what i asked. 1- ___=3

(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

Any questions?
Nnesha
  • 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
pooja195
  • pooja195
You still get the same answer either way.
