A) \[7x=6y\]
B) \[6x=7y\]
C) \[5x=8y\]
D) \[x=0\]
Correct Answer: A
Solution :
Given lines, \[3x-4y=2\] ?.(i) \[x+2y=-4\] ?.(ii) Intersection point of these line is \[3(-4-2y)-4y=2\] \[-12-6y-4y=2\] \[10y=-14\,\,\,\,\Rightarrow \,\,\,y=-7/5\] and \[x=-4-2(-7/5)=-4+14/5\] \[x=-6/5\] Intersection point is \[(-6/5,\,\,-7/5)\]. Now, the equation of the line which passes through the points \[(0,0)\] and \[(-6/5,\,-7/5)\]. \[\Rightarrow \] \[(y-0)+\frac{-7/5-0}{-6/5-0}(x-0)\] \[\Rightarrow \] \[y=\frac{7}{6}.x\] \[\Rightarrow \] \[7x=6y\]You need to login to perform this action.
