Solution

The correct option is A x2y25xy=0
Given equations of curve and the line are 2x2+3xy4x+1=0 and 3x+y=1.
Homogenising the curve with the line gives
2x2+3xy4x(3x+y)+(3x+y)2=0
2x2+3xy12x24xy+9x2+y2+6xy=0
y2x2+5xy=0
The equation of the lines joining the origin to the points of intersection of the curve and hte line is x25xyy2=0
Hence, option A.
