Which three ordered pairs complete the table to give solutions of the equation y = x – 7? A. (–3, –10), (0, –7), and (3, 4) B. (–3, –10), (0, –7), and (3, –4) C. (–3, –4), (0, –7), and (3, –4) D. (–3, 4), (0, –7), and (3, –4)

subtract 7 from the first number if you get the second number you win if not, you lose

OpenStudy (anonymous):

\[-3-7=?\]

Awolflover1 (awolflover1):

-4

OpenStudy (anonymous):

hmm no

OpenStudy (anonymous):

\[3-7=-4\] but not \[-3-7\]

OpenStudy (anonymous):

want another guess or should i say it?

Awolflover1 (awolflover1):

i got -10 you should

OpenStudy (anonymous):

ok so \((-3,-10)\) is the first one now what is \(0-7\)?

Awolflover1 (awolflover1):

-7 ?

Awolflover1 (awolflover1):

@satellite73

Directrix (directrix):

(0, -7) Yes

Directrix (directrix):

Test this: (3, 4) Does 4 = 3 - 7 ?

Directrix (directrix):

Yes or No? If you participate, we can get a wrap on this problem.

Directrix (directrix):

We have two points. We need one more. Is this going to be it: (3, 4)

Awolflover1 (awolflover1):

yes

Directrix (directrix):

No.

Directrix (directrix):

y = x – 7 y = 3 - 7 What is 3 - 7 = ?

Directrix (directrix):

If you need help, copy 3 - 7 = into the Google search box and let the Google calculator tell you.

Awolflover1 (awolflover1):

-4

Directrix (directrix):

So, we know that (-3,-10) and (0, -7) work but this third one (3,4) does not

Directrix (directrix):

The three points (-3,-10) and (0, -7) and the corrected third point ( 3, -4) do work in the equation. Those three points make up an option other than option A. Look at the list of options and post the option that lists these three points. That is your answer to the question.

B

Directrix (directrix):

Correct.
