Question

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

Options

• `y` = 0

• `y` = 1

• `y` = 2

• `y` = 3

Answer 1

`y` = 3

Explanation:

Equation of the plane zox is y = 0

Any plane parallel to it is y = a

It passes through the point (0, 3, 0)

∴ 3 = a

∴ Equation of the required plane is y =3.
