In the Cartesian plane,the vertical line passing through the origin is called the.......

Points $A(5,3)$,$B(-2,3)$,and $D(5,-4)$ are three vertices of a square $ABCD$. Plot these points on a graph paper and hence find the coordinates of the vertex $C$.

State the coordinates of the points shown in the figure below. (The scale on both axes is $1 \,cm = 5$ units.)

The interior of $\angle X'OY'$ is known as the ............ quadrant.

Signs of the abscissa and ordinate of a point in the second quadrant are respectively

The distance between the points $(5, -3)$ and $(5, 8)$ is............
