$A$ point is in the $XZ-$ plane. What can you say about its $y-$ coordinate?

If a line makes angles $90^{\circ}, 135^{\circ},$ and $45^{\circ}$ with the $x, y,$ and $z$-axes respectively,find its direction cosines.

The perpendicular distance of the point $P(6, 7, 8)$ from the $XY$-plane is:

If the direction ratios of a line are $1, -3, 2$,then the direction cosines of the line are

If the projections of the line segment $\overrightarrow{AB}$ on $XY$,$YZ$,and $ZX$ planes are $\sqrt{15}$,$\sqrt{46}$,and $7$ respectively,then the projection of $\overrightarrow{AB}$ on the $y$-axis is

Find the direction cosines of the line passing through the two points $(-2, 4, -5)$ and $(1, 2, 3)$.
