What's the y-intercept?
OpenStudy (anonymous):
Im pretty sure its 2.
OpenStudy (goldphenoix):
Yup. Therefore it's not A.
You know the slope of it?
OpenStudy (anonymous):
Im pretty sure 2/4
OpenStudy (anonymous):
But i thought about it, and you can reduce 2/4 to 1/2

Close, but the line is going down, not up. :)
OpenStudy (goldphenoix):
So it's -1/2.
Therefore C cannot be the answer.
You're now stuck with B and D.
Next, you want to test.
If the origin or (0,0) is shaded, then go test it. ^^
Let's try B
\[\large \large (0) \le-\frac{ 1 }{ 2 }(0) + 2\]
OpenStudy (anonymous):
Ohh.
OpenStudy (goldphenoix):
So what do ya get? :)
OpenStudy (anonymous):
0 is greater but equal 2?

Hmm. Not greater than or equal.
OpenStudy (anonymous):
Less than woops :l
OpenStudy (anonymous):
Less that equal to?
OpenStudy (goldphenoix):
Yep. Now think about it. Is 0 less than or equal to 2?
If it's true, then it's B.
If it's not, it's D.
So what's the answer? ^_^
OpenStudy (anonymous):
0 is less, but isnt equal to 2.
