The equation of a line passing through P (3,4) such that P bisects the part of it intercepted between the coordinate axes is `"_______"`.A. 3x + 4y = 25B. 4x + 3y = 24C. x - y = -1D. x + y = 7

Answer» Correct Answer - B
(i) P is the mid-point of the line joining the inter-cepts. Find the intercepts using the mid-point formula.
(ii) Let the line cut coodinate axes at `A(a,0)` and `B(0,b)`.
(iii) Using the above data find a and b, then the equation of line, i.e, `x/a + y/b = 1`.
