Question:
If in a parallelogram $\mathrm{ABDC}$, the coordinates of $\mathrm{A}$, $B$ and $C$ are respectively $(1,2),(3,4)$ and $(2,5)$, then the equation of the diagonal $\mathrm{AD}$ is:-
$5 x+3 y-11=0$
$3 x-5 y+7=0$
$3 x+5 y-13=0$
$5 x-3 y+1=0$
Correct Option: , 4
Solution:
co-ordinates of point $\mathrm{D}$ are $(4,7)$
$\Rightarrow$ line $\mathrm{AD}$ is $5 \mathrm{x}-3 \mathrm{y}+1=0$
