Question:
If P(-l, 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 fourth quadrant is/are
(a) P and
(b) Q and R
(c) Only S
(d) P and R
Solution:
(b) In point P (-1, 1), x-coordinate is -1 unit and y-coordinate is 1 unit, so it lies in llnd quadrant.
Similarly, we can plot all the points Q (3, -4), R (1, -1), S (-2, -3) and T (-4, 4),
It is clear from the graph that points R and Q lie in fourth quadrant.
