A variable line is drawn through the point (2,1). Perpendiculars are drawn to it from the points (a1,4), (a2,5),(a3,-3) and (2,b1),(3,b2),(7,b3) such that their sum is zero. If all the ai and bi are non-negative real numbers determine their values.
Please reply with explanation..
a1=a2=a3=b1=b2=b3=0 is satisfying the condition.
Thank You
