Question

The equation of a plane which cuts equal intercetps of unit length on the axes, is

• A. $x + y + z = 0$
• B. $x + y + z = 1$
• C. $x + y - z = 1$
• D. $\frac{x}{a} + \frac{y}{a} + \frac{z}{a} = 1$

Answer 1

Answer: (B)

$x + y + z = 1$

Answer 2

Equation of required plane is, $\frac { x } { 1 } + \frac { y } { 1 } + \frac { z } { 1 } = 1$

$\Rightarrow x + y + z = 1$.
