@iGreen.

y = x + 3
The slope here is '1', and that's positive, so the line will rise from left to right..that takes out options A and B.
So we're left with C and D.
OpenStudy (anonymous):
Um, C and D are the same.

Oh wait, nevermind.
OpenStudy (anonymous):
Let's plug in -1 for 'x' into the equation and see what we get.
\(y = x + 3\)
\(y = -1 + 3\)
What's -1 + 3?
OpenStudy (openstudyrocks5*):
-1 + 3 = 2
OpenStudy (openstudyrocks5*):
@iGreen. You there?
OpenStudy (anonymous):
Yes, so when x = -1, y = 2.

So our answer is C, because D says when x = -1, y = 6.
OpenStudy (anonymous):
ok you need help
OpenStudy (openstudyrocks5*):
Yeah I was thinking it was C. anyway :) Thanks for your help IGreen. I may have more questions.
