Which of the following points lie in the solution set to the following system of inequalities? y < -3x + 3 y < x + 2 (1, -5) (1, 5) (5, 1) (-1, 5)

OpenStudy (luigi0210):

Here, have a pretty graph my dear :3

OpenStudy (luigi0210):

Just look for a point that is within the shaded region of the graph~

OpenStudy (accidentalaichan):

Okay, let me try ;-; Thanks, hun~

OpenStudy (luigi0210):

Yea, I see a problem with that.. nvm >.< Hold on.

OpenStudy (accidentalaichan):

It almost looks like (1,5)

OpenStudy (luigi0210):

Wait, I'm right, you have to find a point that's with BOTH shaded regions. And (1, 5) is out of the bounds of both.

OpenStudy (luigi0210):

It would actually be (1, -5)

OpenStudy (luigi0210):

Do see why tho? >_>

OpenStudy (accidentalaichan):

Yeah :3 This is always the hardest part xD

OpenStudy (accidentalaichan):

Let me check

OpenStudy (luigi0210):

Also, if you plug it into the equation.. \[\LARGE y < -3x + 3\] \[\LARGE y < x + 2\] . . \[\LARGE -5<-3(1)+3\] \[\LARGE -5<(1)+2\] . . \[\LARGE -5<0\] \[\LARGE -5<3\]

OpenStudy (accidentalaichan):

I see what I did wrong. I forgot to substitute asdfghjkl

OpenStudy (luigi0210):

Tis okay, at least you know your mistake :)
