Question

The straight line whose sum of the intercepts on the axes is equal to half of the product of the intercepts, passes through the point –

• A. (1, 1)
• B. (2, 2)
• C. (3, 3)
• D. (4, 4)

Answer 1

Answer: (B)

(2, 2)

Answer 2

a + b = Ž 2a + 2b = ab

Let line is $\frac { \mathrm { x } } { \mathrm { a } }$ + $\frac { y } { b }$ = 1 Ž bx + ay = ab

Ž bx + ay = 2a + 2b

b(x – 2) + a(y – 2) = 0
