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

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

Points $(1,-1),(2,-2),(4,-5),(-3,-4)$

The line joining $A (3,-8)$ and $B(3,5)$ intersects the $x$ -axis at $\ldots \ldots . .$

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.
