## Question

### Solution

Correct option is The equation of the given straight line is He equation of the given curve is The combined equation of the straight lines joining the origin to the points of intersection of (i) and (ii) is a homogeneous equation of second degree obtained with the help of (i) and (ii). Making the equation (ii) homogenous of the second degree in x and y with the help of (i), we get  This is the required equation. Comparing this equation with ax2 + 2hxy +by2 = 0, we obtain

a = 7, b = –1 and h = –1
