The correct option (d) (x/2) – (y/3) = 1, {x/(– 2)} + (y/1) = 1
Explanation:
Let equation of line is (x/a) + (y/b) = 1
given is a + b = – 1 hence a = – 1 – b
∴ eqn is [(– x) / (b + 1)] + (y/b) = 1
also line passes through (4, 3)
∴ [(– 4)/(b + 1)] + (3/b) = 1
∴ b = 1 and b = – 3
when b = 1, then a = – 2 and when b = – 3, then a = 2
∴ lines are (x/2) – (y/3) = 1 and [x / (– 2)] + (y/1) = 1
