x + 2y - 8 = 0
2x + y - 8 = 0
2x - y + 8 = 0

Answer 1

bottom one rite?

Answer 2

y = -2x + 8, rewrite that to suit one of the answers

Answer 3

2x-y+8=0

Answer 4

2x -y + 8 = 0 => -y = -2x - 8 => y = 2x + 8

Answer 5

so im right?

Answer 6

nope, the one you're looking for is y = -2x + 8

Answer 7

then it would be the second one

Answer 8

yup :)
