Answer:
lower-right (see attached)
Explanation:
We notice the y-variable has a positive coefficient in both equations, so we need only look at that in relation to the inequality symbol:
y ≥ ... ⇒ shading will be above a solid line
y < ... ⇒ shading will be below a dashed line
__
A dashed line shows up only in the first and last choices. Shading above only shows up in the last choice.
