Question

Find the equation of the plane with intercept 3 on the y-axis and parallel to ZOX plane.

• A. $x=1$
• B. $x=2$
• C. $y=2$
• D. $y=3$

Answer 1

The correct option is D $y=3$

The equation of the plane ZOX is :

$y=0$

Any plane parallel to it is of the form, $y=a$

Since the y-intercept of the plane is 3,

Therefore, $a=3$

Thus, the equation of the required plane is $y=3$.
