do you understand how slope-intercept formula works?
if you do, it might be easier to look at the given options that way.

the slope-intercept formula is y=mx+b right??

jigglypuff314 · Answer

yes :) so... 
x + y - 2 = 0      =>         y = -x + 2
x - y - 2 = 0       =>        y = x - 2
x + y + 2 = 0      =>        y = -x -2
so now which one do you think matches the graph?

umm... the last one?? ):

jigglypuff314 · Answer

yep :) :D

omg really?? :D thank you so much!

jigglypuff314 · Answer

it was because b = y-intercept = -2
 and slope m = -1
