Which three ordered pairs complete the table to give solutions of the equation y = x – 7?
Options-
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)

Answer 1

HELP!!

Answer 2

Ok. Let's choose x = 1, what is y ?

Answer 3

?

Answer 4

Can you give me the solution to the answer????

Answer 5

Nope, you should solve it, I can help you.

Answer 6

I dont get it!! Thats why!

Answer 7

Ok, the eqn is y = x -7. right ?

Answer 8

yes

Answer 9

Now put x= 1 in the eqn
you get y = 1-7

Answer 10

ok...

Answer 11

Tell me what is y

Answer 12

1-7?

Answer 13

1- 7 = -6

Answer 14

Choose some other values of x and find y

Answer 15

Your first ordered pair is (1,-6)

Answer 16

ok

Answer 17

But my options are-
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)

Answer 18

You have 3 ordered pairs in each solution.

You have to find the option in which the 3 ordered pairs match the equation.

Remember that an ordered pair is in the form (x , y) where x is the first term, and then y is after the comma.

therefore you take each ordered pair, starting with the first one and we have (-3, -10)
so
x = -3
y = -10

Now if we plug these values into the equation, does it prove true?
y = x -7
-10 = -3 - 7

so this is true, so you have your first ordered pair checks out. Now you have to check the rest of them, until you find the option where all 3 are correct.

Answer 19

I'm pretty sure its B. I graphed it.

Answer 20

Yes, it's B. Good Job ! @lizziebeth
