Question

Write the equation of the plane parallel to XOY- plane and passing through the point (2, −3, 5).

Answer 1

$$\begin{gathered} \text{The equation of the plane parallel to the plane}\mathit{\text{XOY}}\text{\hspace{0.17em}is} \\ z=b...\left(1\right),\text{where}\mathit{\text{b}}\text{is a constant.} \\ \text{It is given that this plane passes through (2,-3, 5). So,} \\ 5=b \\ \text{Substituting this value in (1), we get} \\ z=5,\text{which is the required equation of the plane.} \end{gathered}$$
