Find the equations of the straight lines which pass through the origin and trisect the portion of the straight line 2x+3y=6 which is intercepted between the axes
Let the equation of the line be
As P trisects the line AB, therefore, coordinates of P are
Similarly, Q also trisects the line AB. Therefore, coordinates of Q are
Thus, equation of line OP is given by
∴x - 3y = 0.....(1)
Equation of line OQ is given by
∴4x - 3y = 0.....(2)
Lines (1) and (2) pass through the origin and trisect the portion of the line 2x + 3y = 6.
