Plug in a few points that lie below line c, such as (0, −1), (−3, −4), (1, 0). In each case, the x-coordinate is greater than the y-coordinate, so Quantity A is greater. Alternatively, realize that the 45 degree angle and the fact that the line passes through the origin tells us that the equation of line c is y = x. So the region below the line is the graph of y < x. The coordinates of all points in that region must satisfy the inequality.
