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

Point $(2.8,4.9)$ lies in the $\ldots \ldots . .$ quadrant.

If $P (-1,1), Q(3,-4), R (1,-1), S (-2,-3)$ and $T (-4,4)$ are plotted on the graph paper, then the points in the fourth quadrant are

Taking $0.5\, cm$ as $1\, unit,$ plot the following points on the graph paper :

$A (1,3), B (-3,-1), C (1,-4), D (-2,3), E (0,-8), F (1,0)$

Without plotting the points indicate the quadrant in which they will lie, if

$(i)$ ordinate is $5$ and abscissa is $-3$

$(ii)$ abscissa is $-5$ and ordinate is $-3$
