Hey! So I'm horrible when it comes to graphing inequalities, I'm good at solving them, just not graphing them. Could I have some help with this question?
Which inequality matches the graph?
<--|------|------|------|------O
-3 -2 -1 0 1
A. 3x + 1 > 4
B. 3x + 1 ≥ 4
C. 3x + 1 < 4
D. 3x + 1 ≤ 4
Can someone just explain how the graph thing works?

Looks like your little circle is open and your line goes to the left,
so you must be looking at
x < 1
Had it been a solid circle the solution would show
x ≤ 1
You have to know and decide if it is open or closed (solid).
You said you were good at solving them, so which one gave you
that solution?
