Answer 1

Which of those goes past the origin?

Answer 2

Origin= point (0,0)

Answer 3

im really stuck on this one,lol

Answer 4

y = –2x + 23
y = – 3x + 4
y = 3x – 12

Do you notice that these have all different y intercepts?

Answer 5

yes

Answer 6

Hmm, let me graph this and let you look at it. Give me a minute.

Answer 7
