Answer 1

i don't know

Answer 3

get y alone first :)

Answer 4

y=mx+b form?

Answer 5

yeah, just isolate y
subtract both sides by 4

Answer 6

y+4=0 subtract 4 from both sides
-4 -4
y = -4

you can look at it like y = 0x - 4

Answer 7

so, its A?

Answer 8

not quite :)

Answer 9

:(

Answer 10

y = mx + b
y = 0x - 4

Answer 11

so, I add 4?

Answer 12

no, you just see how they line up and decide what m and b equal

Answer 13

ok

Answer 14

m=0 b=4

Answer 15

B?

Answer 16

yep :)

Answer 17

Yay!

Answer 18

Thank you!
