two straight lines passing through the point a 32 cut the

Two straight lines passing through the point $$A\left( {3,\,2} \right)$$ cut the line $$2y = x + 3$$ and $$x$$-axis perpendicularly at $$P$$ and $$Q$$ respectively. The equation of the line $$PQ$$ is :

A. $$7x + y - 21 = 0$$

B. $$x + 7y + 21 = 0$$

C. $$2x + y - 8 = 0$$

D. $$x + 2y + 8 = 0$$

Answer : $$7x + y - 21 = 0$$

Solution :

$$\because $$ Coordinates of $$Q$$ are $$\left( {3,\,0} \right)$$ & it passes through $$PQ.$$
$$\therefore $$ Putting the values of $$\left( {x = 3} \right)\& \left( {y = 0} \right)$$ in options we get :
Equation of line $$PQ = 7x + y - 21 = 0$$
