Answer 1

First find the equation of the boundary line, which is x=2 for this problem.

If the inequality is \(\le\) or \(\ge\), the line is full (i.e. not dotted).
If it is a strict inequality, \(\lt\) or \(\gt\) , the line is dotted.
To determine whether it is smaller or greater, go with the location of the region with respect to the boundary line:
left or bottom means less than/less than or equal
right or top means greater than/greater than or equal.

Answer 2

So, D.?

Answer 3

not quite! :(
Hints:
"If the inequality is ≤ or ≥, the line is full (i.e. not dotted).
If it is a strict inequality, < or > , the line is dotted."
