The coordinates of a point are the perpendicular distance from the ............ on the respectives axes.
Explanation
Given points
38
The three coordinate planes divide the space into ............ parts.
Explanation
Eight parts
39
If a point $P$ lies in $Y Z$-plane, then the coordinates of a point on $Y Z$-plane is of the form ........... .
Explanation
We know that, on $YZ$-plane, $x=0$. So, the coordinates of the required point is $(0, y, z)$.
40
The equation of $Y Z$-plane is ............. .
Explanation
The equation of $Y Z$-plane is $x=0$.
41
If the point $P$ lies on $Z$-axis, then coordinates of $P$ are of the form ......... .
Explanation
On the $Z$-axis, $x=0$ and $y=0$. So, the required coordinates are $(0,0, z)$.
