The ordinate of all points on the $x$-axis is:

The point $(-10, 0)$ lies:

If the point $(a, 0)$ is on the ray $OX^{\prime}$,is $a$ a positive number or a negative number?

The point at which the two coordinate axes meet is called the

If $(2a + 5, 3b + 2)$ and $(a + 11, b + 14)$ are coordinates of the same point,then the values of $a$ and $b$ are $\ldots$ respectively.

The point $(0, -7)$ lies:
