A) \( \Large 7x-24y=0 \) |
B) \( \Large 24x-7y=0 \) |
C) \( \Large 7x+24y=0 \) |
D) \( \Large 24x+7y=0 \) |
D) \( \Large 24x+7y=0 \) |
Centre'of the circle is \( \Large \left(3,\ 4\right) \) and it passes through the origin, If \( \Large y = mx \) is the equation of the required line, then length of' the perpendicular from the centre on this line is equal to the length of the perpendicular from the centre on the axis of x.
= \( \Large \frac{3m-4}{\sqrt{1+m^{2}}}= \pm 4 \)
=> \( \Large 9m^{2}-4m+16 = 16 \left(1+m^{2}\right) \)
=> \( \Large m = -\frac{24}{7} \) (\( \Large \therefore\ m = 0 \) corresponds to x-axis)
and hence, the required equation is \( \Large 24x +\ 7y = 0 \)
