1.  None of them, unless some of them are "or equals to".  If they are all greater than or less than, then it doesn't include the line.  But I think it's the one that has the same equation 2x+1, so B

2. Plug the x values in and which ever one gives you the y value is the right answer

3. Put the original equation in the same format as all the answers.  Then take a point that fits the description (above the line . . . ) and try it in the original equation.

4. Plug in (0, 0) into each answer choice.  The answer choice that is true is the answer to your question.
