Question

A plane $\pi$ makes intercepts 3 and 4 respectively on z-axis and x-axis. If $\pi$ is parallel to y-axis, then its equation is

• A. $3x + 4z = 12$
• B. $3z + 4x = 12$
• C. $3y + 4z = 12$
• D. $3z + 4y = 12$

Answer 1

Answer: (A)

$3x + 4z = 12$

Answer 2

X-intercept $( a ) = 4$ Z-intercept$( c ) = 3$

Required equation = $\frac { x } { 4 } + \frac { z } { 3 } = 1$ or $3 x + 4 z = 12$ .
