The vertex of a rectangle are (1, 0), (9, 0), (1, 4) and (9, 4) respectively. If line L passes through the origin and divided the rectangle into two identical quadrilaterals, what is the slope of line L?	Choose the correct answer.
A) 4 B) 2 C) 1/4 D) 2/5 E) 5/6
If line L divides the rectangle into two identical quadrilaterals, then it must pass through the center (5, 2). The slope of a line passing through (0,0) and (5, 2) is 2/5.   The answer is 2/5.
