The point $\left(-\frac{7}{2}, \frac{5}{2}\right)$ lies in the $\ldots \ldots \ldots$ quadrant.

Write whether the following statements are True or False. Justify your answer.
$(i)$ The coordinates of a point whose ordinate is $-\frac{1}{2}$ and abscissa is $1$ are $(-\frac{1}{2}, 1)$.
$(ii)$ $A$ point lies on the $y$-axis at a distance of $2$ units from the $x$-axis. Its coordinates are $(2, 0)$.

The distance of the point $(7,0)$ from the origin is $\ldots \ldots$

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

If $a=5, b=3, c=-8$ and $d=-5$,then in which quadrant does the point $(a+c, b+d)$ lie?

In which quadrant or on which axis does each of the following points lie?
$A(5, 0), B(3, -2), C(-2, 5), D(0, 4), E(-3, -4), F(4, 3), G(0, -4), H(-5, 0)$
