Question

Graph x<2, need help on this one please.

Answer 1

Okay. So, the line shaded would have to be left to 2, because it's less than 2. In that case, A and C are eliminated, because they shade to the right, not left. B and D do this, but wait. The dotted line has to represent the less than, because the one that's fully filled in would mean less than or equal to. B would make sense, because the line is dotted and that makes an inequality symbol of less than, not less than or equal to. The answer is B.

Note: When the sign is < or >, the line on the graph is dotted. If the sign is <= or >=, then the line on the graph is solid.
