1.Points A and B are in the first quadrant, so that OA=OB (where O is the origin). If the slope of line OA is 1 and the slope of line OB is 41, then find the slope of line AB.

If a, b, c are nonnegative integers, b and c are relatively prime, and a + b/c = a*b/c, then what is b - c?

Let P=(0,6), Q=(12,0), and R=(0,0). A line passing through the point (3,0) bisects the area of the triangle. Find the slope of this line.
