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.

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

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

Which quadrant does the interior of $\angle X^{\prime}OY^{\prime}$ represent?

Plot the following points and check whether they are collinear or not:
$(1,3), (-1,-1), (-2,-3)$

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 $C$.
