A.
(–3, –7), (0, –4), and (3, –1)

B.
(–3, –7), (0, –4), and (3, 1)

C.
(–3, –1), (0, –4), and (3, 1)

The ordered pairs go in (x,y) order.  So if you plug in the x coordinate for x into the equation, and the y coordinate for y in the equation, you would be able to see which ones are true.

k_lynn · Answer

So if you plug in -3 in for x in the equation, and -7 for y, the equation should look like this: $$(-7)=(-3)+4$$  Is that equation true?

k_lynn · Answer

oops.  $$(-7)=(-3)-4$$

anonymous · Answer

No. :O

anonymous · Answer

So that leaves us with C and D.

anonymous · Answer

I think its D?;S

k_lynn · Answer

Ack, I'm being a goon today :/.  Actually subtract (-3)-4 again.  Do you get -7?
