Question

If a, b, c are in H.P., then the straight line $\frac { \mathrm { x } } { \mathrm { a } } + \frac { \mathrm { y } } { \mathrm { b } } + \frac { 1 } { \mathrm { c } }$ = 0 always passes through a fixed point and that point is

• A. (–1, –2)
• B. (–1, 2)
• C. (1, –2)
• D. $\left( 1 , \frac { 1 } { 2 } \right)$

Answer 1

Answer: (C)

(1, –2)

Answer 2

$\frac { 1 } { a } - \frac { 2 } { b } + \frac { 1 } { c } = 0$

The line $\frac { x } { a } + \frac { y } { b } + \frac { 1 } { c } = 0$ passes through the pt

(1, –2)
