Equation of line in Straight lines
Question

The equation of straight line passing through (a,0) and making the triangle with axes of area T is

Easy
Solution

If the line cuts off the axes at A and B, then area of triangle is 12×a×OB=TOB=2Ta 

Hence, the equation of line is  xa+y2T/a=1

   2Txa2y+2aT=0
