The point of intersection of the $x$ -axis and the $y$ -axis is called $\ldots .$

The points $(-5,2)$ and $(2,-5)$ lie in the

If $a=5, b=7, c=6$ and $d=10,$ then the point $(a-b, c-d),$ is the point of the ……… quadrant.

If $a=5, b=7, c=3$ and $d=-5,$ then the point $\left(\frac{a}{b}, \frac{c}{d}\right)$ is in the $\ldots \ldots . .$ quadrant.

The line joining $X(3,5)$ and $Y(-4,5)$ is parallel to the $\ldots \ldots \ldots$ axis.
