The easiest way to solve this problem is to draw the xy-plane with each of the points in the answer choices plotted.
Drawing a line between (1, 1) and choice (A) would produce a vertical line (infinite or undefined slope).
Drawing a line between (1, 1) and choice (B) would produce a line with negative slope (-1).
Drawing a line between (1, 1) and choice (C) would produce a line with positive slope 1/3
Drawing a line between (1, 1) and choice (D) would produce a line with negative slope - 1/3
Therefore, choices (B) and (D) satisfy the conditions in the problem.
