Consider a sequence of line drawings. Figure 1 is two parallel lines (0 intersections). Figure 2 is two intersecting lines (1 intersection). Figure 3 is three lines meeting at a single common point (1 intersection). Figure 4 is three lines where each line intersects every other line at a unique point (3 intersections). If Figure 5 consists of four straight lines where no two lines are parallel and no three lines meet at a single point, what is the maximum number of intersection points in Figure 5?
