Answer:
C
Step-by-step explanation:
First, graph the equation:
The y-intercept is -4.
And the slope is 1/2, an upward sloping line.
So, our graph should be either A, B, or C.
D is not correct, so eliminate that.
So, our inequality is:

Note that this inequality is strictly less than. There's no "or equal to" bar. Therefore, our line should be dotted.
Thus, eliminate A and B.
So, C is our answer
Further notes:
The inequality sign means that y is <em>less than</em> the equation. In other words, our shaded region should be <em>below </em>the line.
In C, the shaded area is indeed below the line.
So, C is indeed our answer :)
