Line a passes through (2,3) and (6,5) on a coordinate plane. Lines b, c, and d are defined by the ordered pairs below. Line b passes through (-2,1) and (4,4). Line c passes through (8,6) and (-1,-3). Line d passes through (-4,2) and (2,5). Determine whether lines b, c, and d form lines that intersect line a at no points, one point, or infinitely many points. Write the name of the point in the appropriate box.
