The answer is B. The dotted line tells you that the equations will be "greater than" or "less than". A solid line would indicate that it would be "greater than or equal to" or "less than or equal to". Then, since C and D can be eliminated, you look at which equations graphs the line. The answer must be B because the y-intercept is -1 (remember that the equation of a line is y = mx + b, where b is the y-intercept).
