Question

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 point(s) in the third quadrant are:

• A. $P$ and $T$
• B. $Q$ and $R$
• C. Only $S$
• D. $P$ and $R$

Answer 1

The correct option is B $Q$ and $R$

We know that in third quadrant both the coordinates i.e, $x,y$ are negative.

Now the given points are

$P(1,1),Q(-3,-4),R(-1,-1),S(2,3)$ and $T(4,4)$.

Among them, $Q$ and $R$ have both the coordinates negative.

$\therefore$ points $Q$ and $R$ are in third quadrant.
